how to create documentation to a function library in matlab

In MATLAB, you can create documentation for a function library by using the built-in function help and by following the standard MATLAB documentation format. Here are the steps:

1. Create a folder for your function library and save all your functions in that folder.

2. Open any MATLAB function from your library. Add comments to the function file in the following format:

main.m
%{
    FunctionName - One-line description of the function
    --------------------------------------------------
    Syntax: 
    --------
        function [output_args] = FunctionName(input_args)
    Input:
    -------
        input_args  - (description)
    Output:
    -------
        output_args - (description)
    Example:
    ---------
        describe how to use the function with an example
%}
404 chars
17 lines

3. Save the function file.

4. Now, open MATLAB and navigate to the folder containing your function library.

5. Type help FunctionName in the MATLAB command window, MATLAB will display the documentation you added to your function.

6. You can also generate the HTML documentation for all your functions using the MATLAB help browser. Click on "Publish" from the "Editor" tab on the MATLAB toolstrip and select "Generate MATLAB function help".

7. You can now share the HTML documentation with your team or users.

Make sure to follow standard MATLAB documentation format to make your documentation consistent and readable.
