Custom header for bus object m-file

I am saving bus objects to a .m file. When I save, Matlab autogenerates the below header in that .m file:

% -------------------------------------------------------------------

% Generated by MATLAB on 23-Feb-2021 14:36:37

% MATLAB version: 9.6.0.1072779 (R2019a)

% -------------------------------------------------------------------

Can I customize that comment header? I would like to add some additional text to it.

Hi Jennifer Bennington,

I understand you have a query regarding generating a custom header in .m file. You can write a MATLAB script that reads the generated .m file, adds a custom header, and then writes the content back to the file. Here's an example script that does this:

function addCustomHeaderToFile(filename, headerText) 
    % Read the existing content of the file 
    originalContent = fileread(filename); 
    % Define a custom header 
    timestamp = datestr(now, 'dd-mmm-yyyy HH:MM:SS'); 
    header = sprintf(['%% Custom Header - Generated on %s\n'... 
                      '%% MATLAB version: %s\n'... 
                      '%s\n\n'], timestamp, version, headerText); 

    % Concatenate the custom header with the original file content 
    newContent = [header originalContent]; 
    % Write the new content back to the file 
    fileId = fopen(filename, 'w'); 
    fwrite(fileId, newContent); 
    fclose(fileId); 
end 

After saving your bus object to the .m file, call the “addCustomHeaderToFile” function with the filename and your custom header text:

% Define custom header text 
myHeaderText = 'This code was autogenerated by a script. Do not modify manually.'; 
% Call the function to add the header 
addCustomHeaderToFile('MyBusObjectFile.m', myHeaderText);
