Parts of Variables in MAT-Files.In MATLAB Online™, variables persist between sessions. Saving allows you to clear the workspace and load variables at a later time. To save variables, use the save or matfile functions.Load Workspace VariablesTo load saved variables from a MAT-file into your workspace, double-click the MAT-file in the Current Folder browser.To load a subset of variables from a MAT-file on the Home tab, in the Variable section, click Import Data. Select the MAT-file you want to load and click Open. You also can drag the desired variables from the Current Folder browser Details panel of the selected MAT-file to the Workspace browser. In MATLAB Online, you also can click the Preview button to the right of the MAT-file in the Files browser and drag the desired variables from the preview to the Workspace panel.To load variables saved to a MATLAB script into the workspace, simply run the script.You also can load saved variables programmatically, use the load function. For example, load all variables from the file durer.matTo load variables X and map from the file durer.matTo load part of a variable, use the matfile function. This is 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 Parts of Variables in MAT-Files.CautionWhen you load data into the MATLAB workspace, the new variables you create overwrite any existing variables in the workspace that have the same name. To avoid overwriting existing variables, use the load function to load the variables into a structure. For example, S = load('durer') loads all the variables from the file durer.mat into the structure S.View Contents of MAT-FileTo see the variables in a MAT-file before loading the file into your workspace, click the file name in the Current

Hi John,When you rename a class or move it into a namespace, MATLAB does not automatically recognize the new class definition when loading old .mat files containing objects of the original class. However, you can use MATLAB's matfile and loadobj functionalities to handle this situation.Scenario 1: Renaming the ClassDefine the new class with a loadobj method: Create a loadobj method in your new class definition to handle the conversion from the old class to the new class. function obj = my_class_ver1() function obj = loadobj(a) 2. Load the .mat file: When you load the .mat file, MATLAB will call the loadobj method to convert the objects.data = load('my_data.mat');Scenario 2: Introducing NamespacesDefine the new class within the namespace with a loadobj method: Create a loadobj method in your new class definition within the namespace to handle the conversion. function obj = my_class() function obj = loadobj(a) 2. Load the .mat file: Similar to the first scenario, MATLAB will call the loadobj method to convert the objects when you load the file.data = load('my_data.mat');Important Points to consider:Ensure that the properties and methods of the new class match those of the old class to facilitate smooth conversion.You might need to manually copy the properties from the old object to the new object within the loadobj method.This approach requires you to have access to the old class definition during the transition period. If the old class definition is not available, you will need to manually handle the conversion.

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

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.

Hi All Matlab users,I have an image in .mat file ... I have a problem with display it.clear all;I=load ('Data.mat'); % struct double 512x512I=I.s.I;I=double(I);figure(1);imshow(I);Could someone help me please ?I would appreciate for any help. Accepted Answer Why don't you just do something like% Load entire mat file contents into a structure.% The structure has a member "I" that is a double 512x512 array.storedStructure = load('Data.mat');% Extract out the image from the structure into its own variable.% Don't use I as the variable name - bad for several reasons.imageArray = storedStructure.s.I; % Or storedStructure.I depending on what members your structure has.% Display the image in a brand new figure window.figure(1);% Display double image, scaled appropriately.% No need to cast to uint8 - could even be bad% if your double numbers don't span the 0-255 range nicely.imshow(imageArray, []); More Answers (4) It is not good . I received en error : ??? Error using ==> uint8 Conversion to uint8 from struct is not possible.I = load('Data.mat'); figure(1); imshow(uint8(I));????
