how to run a file in matlab

To run a MATLAB file, you can either run a script or a function. The process of running them is quite similar.

1. To run a script, you simply need to open the file and click the "Run" button in the toolbar, or type the name of the file in the Command Window and press enter.

main.m
% Example of running a script
% Open the file
edit myScript.m

% Run the file
run myScript.m
93 chars
7 lines

2. To run a function, you will need to first save the file with the function with the same name as the file name.

main.m
% Example of running a function
% Save this function as "myFunction.m"
function output = myFunction(input)
    output = input + 1;
end

% Call the function
myVariable = myFunction(5); % This should return 6
207 chars
9 lines

3. You can also run a MATLAB file from the command-line by using the -r option followed by a string that includes the commands to run.

main.m
% Example of running a script from command line
% Open a terminal window and type:
matlab -r "run('myScript.m');"

% Example of running a function from command line
matlab -r "output = myFunction(5);disp(output);"
