Documentation Examples Functions Videos Answers Main Content Run a Batch JobTo offload work from your MATLAB® session to run in the background in another session, you can use the batch command inside a script.To create the script, type:In the MATLAB Editor, create a for-loop:for i = 1:1024 A(i) = sin(i*2*pi/1024);endSave the file and close the Editor.Use the batch command in the MATLAB Command Window to run your script on a separate MATLAB worker:batch does not block MATLAB and you can continue working while computations take place. If you need to block MATLAB until the job finishes, use the wait function on the job object.After the job finishes, you can retrieve and view its results. The load command transfers variables created on the worker to the client workspace, where you can view the results:When the job is complete, permanently delete its data and remove its reference from the workspace:batch runs your code on a local worker or a cluster worker, but does not require a parallel pool.You can use batch to run either scripts or functions. For more details, see the batch reference page.Run a Batch Job with a Parallel PoolYou can combine the abilities to offload a job and run a loop in a parallel pool. This example combines the two to create a simple batch parfor-loop.To create a script, type: In the MATLAB Editor, create a parfor-loop:parfor i = 1:1024 A(i) = sin(i*2*pi/1024);endSave the file and close the Editor.Run the script in MATLAB with the batch command. Indicate that the script should use a parallel pool for the loop:job = batch('mywave','Pool',3)This command specifies that three workers (in addition to the one running the batch script) are to evaluate the loop iterations. Therefore, this example uses a total of four local workers, including the one worker running the batch script. Altogether, there are five MATLAB sessions involved, as shown in the following diagram.To view the results:wait(job)load(job,'A')plot(A)The results look the same as before, however, there are two important differences in execution:The work of defining the parfor-loop and accumulating its results are offloaded to another MATLAB session by batch.The loop iterations are distributed from one MATLAB worker to another set of workers running simultaneously ('Pool' and parfor), so the loop might run faster than having only one worker execute it.When the job is complete, permanently delete its data and remove its reference from the workspace:Run Script as Batch Job from the Current Folder BrowserFrom the Current Folder browser, you can run a MATLAB script as a batch job by browsing to the file's folder, right-clicking the file, and selecting . The batch job runs on the cluster identified by the default cluster profile. The following figure shows the menu option to run the script file script1.m:Running a script as a batch from the browser uses only one worker from the cluster. So even if the script contains a parfor loop or spmd block, it does not open an additional pool of workers on the cluster. These code blocks execute on the single

Matlab m files and scripts

Scripts are the simplest kind of code file because they have no input or output arguments. They are useful for automating series of MATLAB® commands, such as computations that you have to perform repeatedly from the command line or series of commands you have to reference.You can create a new script in the following ways:Highlight commands from the Command History, right-click,and select . On the Home tab, click the New Script button.Use the edit function. For example, edit new_file_name creates(if the file does not exist) and opens the file new_file_name.If new_file_name is unspecified, MATLAB opensa new file called Untitled.After you create a script, you can add code to the script and save it. For example, you can save this code that generates random numbers from 0 through 100 as a script called numGenerator.m.columns = 10000;rows = 1;bins = columns/100;rng(now);list = 100*rand(rows,columns);histogram(list,bins)Save your script and run the code using either of these methods:Type the script name on the command line and press Enter.For example, to run the numGenerator.m script,type numGenerator.On the Editor tab, click the Run button.You also can run the code from a second code file. To do this, add a line of code with the script name to the second code file. For example, to run the numGenerator.m script from a second code file, add the line numGenerator; to the file. MATLAB runs the code in numGenerator.m when you run the second file.When execution of the script completes, the variables remain in the MATLAB workspace. In the numGenerator.m example,

Remote Cluster Without a Shared File SystemMATLAB uses files on disk to send tasks to the Parallel Server workers and fetch their results.This is most effective when the disk location is accessible to your machine and the workers on the cluster.Your computer can communicate with the workers by reading and writing to this shared file system.If you do not have a shared file system, MATLAB uses SSH to submit commands to the scheduler and SFTP (SSH File Transfer Protocol) to copy job and task files between your computer and the cluster.To configure your cluster to move files between the client and the cluster with SFTP, set the RemoteJobStorageLocation field of AdditionalProperties to a folder on the cluster that the workers can access.Transferring large data files (for example, hundreds of MB) over the SFTP connection can add a noticeable overhead to job submission and fetching results.For optimal performance, use a shared file system if one is available.The workers require access to a shared file system, even if your computer cannot access it.Save New ProfileIn the Cluster Profile Manager, click Done.Alternatively, in the Command Window, enter the command:saveAsProfile(c, 'myPBSCluster');Your cluster profile is now ready to use.Validate Cluster ProfileCluster validation submits one job of each type to test whether the cluster profile is configured correctly.In the Cluster Profile Manager, click Validate.If you make a change to a cluster profile, run cluster validation to ensure your changes have introduced no errors.You do not need to validate the profile each time you use it or each time you start MATLAB.ExamplesCreate a cluster object using your profile:c = parcluster("myPBSCluster")Submit Work for Batch ProcessingThe batch command runs a MATLAB script or function on a worker on the cluster.For more information about batch processing, see the documentation for batch.% Create a job and submit it to the cluster.job = batch( ... c, ... % Cluster object created using parcluster @sqrt, ... % Function or script to run 1, ... % Number of output arguments {[64 100]}); % Input arguments% Your MATLAB session is now available to do other work, such% as create and submit more jobs to the cluster. You can also% shut down your MATLAB session and come back later. The work% continues running on the cluster. After you recreate the% cluster object using parcluster, you can view existing jobs% using the Jobs property of the cluster object.% Wait for the job to complete. If the job is already complete,% the wait function will return immediately.wait(job);% Retrieve the output arguments for each task. For this example,% the output is a 1x1 cell array containing the vector [8 10].results = fetchOutputs(job)Open Parallel PoolA parallel pool (parpool) is a group of MATLAB workers on which you can interactively run work.When you run the parpool command, MATLAB submits a special job to the cluster to start the workers.Once the workers start, your MATLAB session connects to them.Depending on the network configuration at your organization, including whether it is permissible to connect to a program running on a compute node, parpools. 1.3.

Program files that can include formatted text, images, and output to explain the code Live scripts and live functions are program files useful for interacting with a series of MATLAB® commands. Live scripts contain output and graphics with the code that produced them, together in a single interactive environment called the Live Editor. Live functions provide additional flexibility, allowing you to pass input values and return output values. You can add formatted text, images, hyperlinks, and equations to live scripts and functions to produce an interactive narrative that can be shared with others. For more information about live scripts and functions, including incompatibilities and information about the Live Code file format, see What Is a Live Script or Function?

What are the rules for naming script files? - MATLAB Answers - MATLAB

The workspace is not maintained across sessions of MATLAB®. When you quit MATLAB, the workspace clears. However, you can save any or all the variables in the current workspace to a MAT-file (.mat). You can then reuse the workspace variables later during the current MATLAB session or during another session by loading the saved MAT-file.Save Workspace VariablesThere are several ways to save workspace variables interactively:To save all workspace variables to a MAT-file, on the Home tab, in the Variable section, click Save Workspace.To save a subset of your workspace variables to a MAT-file, select the variables in the Workspace browser, right-click, and then select . You also can drag the selected variables from the Workspace browser to the Current Folder browser.To save variables to a MATLAB script, click the Save Workspace button or select the option, and in the Save As window, set the Save as type option to . Variables that cannot be saved to a script are saved to a MAT-file with the same name as that of the script.You also can save workspace variables programmatically using the save function. For example, to save all current workspace variables to the file june10.mat, use the commandTo save only variables A and B to the file june10.mat, use the commandTo store fields of a scalar structure as individual variables, use the save function with the -struct option. This can be useful if you previously loaded variables from a MAT-File into a structure using the syntax S = load(filename) and want to keep the original variable structure when saving to a new MAT-File.To save part of a variable, use the matfile function. This can be useful if you are working with very large data sets that are otherwise too large to fit in memory. For more information, see Save and Load. 1.3.

In today’s post, Owen Paul joins us to share some of the most popular YouTube videos on MATLAB’s “How-To” Playlist for beginners to help you get started on your MATLAB journey. Over to you, Owen..—You are sitting in front of a computer with a blank MATLAB screen in front of you. You have an assignment you need to finish but no clue where to start. Everything made sense when the professor was explaining the functions in class but now that you’re on your own, MATLAB looks like another language. We’ve all been there. Because learning any coding language or program is the same as learning a new language.As a visual learner, I always click on shorter videos when searching for MATLAB help. That’s why I wanted to share 6 short videos that you can use to help you learn the basics needed for working in MATLAB. Whether you’re new to MATLAB or want to learn new features to make coding faster, these videos are for you. All the videos come from the How-to Playlist on the MATLAB YouTube Channel. For more short instructional videos on MATLAB and Simulink, be sure to check it out.Live Scripts The first step to coding, is creating a new script to save all your code. Generally, people work with a regular MATLAB script (.m), which allows for code and comments. But MATLAB scripts are so last century. MATLAB Live Scripts (.mlx) enable you to have code, comments, text, and pictures all in one file. This makes it easy to create and document reports and assignments. Learn how to use live scripts in this first video.Scalar vs. Vector operations To use the dot operator or not to use the dot operator. This is a question that engineering students worldwide have been pondering since the beginning of time. This next video intends to break this cycle of confusion. This video demonstrates the difference between scalar, vector, and matrix variables and the operators necessary when working with each data type.Indexing Data Sets You now know how to divide matrices, but now you need the last 3 columns from the resulting matrix. Indexing data can take anywhere from a couple lines of code toover30. If it’s the latter, sorry to burst your bubble but you are probably doing too much work. There’s plenty of functions and features that MATLAB offers that allow you to quickly search and index large data sets. Learn how, in this next video.Importing Excel DataThese past couple videos have demonstrated how to work with data, but what do you do if that data is in excel? Import it! Excel is a great tool, but MATLAB offers a lot more features for data analysis and visualization. To leverage these features, you must import the data into MATLAB. You can do this without writing any code, and this next video will show you how.Debugging MATLAB Code If you’ve written any code by this point you have probably run into a few errors in your code. Finding and
