I cannot get my userdefined m-function help by the ‘help xxx ’ command in Command window.

As the Official Help Document show （figure1 below），I copy the m-function addme and save the file to my workdir.

However, when type 'help addme' in Command window , I only get the result as 'addme is a function'(figure 2 below).

As show in figure 3 , the help report result of my workdir shows that there is no help in my code.

How can I get my my userdefined m-function help ?

I tried running it and it worked correctly.

I got the above output.

I suggest you try it out once again. It should work in the intended way.

This problem may be due to a path setting error. Due to the need for co-simulation with other simulation software, I added the relevant paths of Siemens PreScan into the MATLAB path, resulting in that all the help information added in the m file could not be indexed in the command window and help report. After deleting these relevant paths, the help information could be retrieved again.
