Help is no longer showing up for user written programs. For example using the function addme as described in matlabs documentation on "Add Help to Prgorams" this is what whos up in command window
>> help addme
addme is a function.
c = addme(a, b)
Below is actual program file:
function c = addme(a,b)
% ADDME Add two values together.
% C = ADDME(A) adds A to itself.
%
% C = ADDME(A,B) adds A and B together.
%
% See also SUM, PLUS.
switch nargin
case 2
c = a + b;
case 1
c = a + a;
otherwise
c = 0;
end
Documentation says that this is what should appear in command window:
When you type help addme at the command line, the help text displays in the Command Window:
addme Add two values together.
C = addme(A) adds A to itself.
C = addme(A,B) adds A and B together.
See also sum, plus.
Using Matlab version 2023b. This problem just started happening. Always worked properly before.

What if you expressly run help.m? Maybe the RptgenSL p file is getting in the way???

help addme won't be affected by the method on RptgenSL objects as 'addme' is not one of those objects.
To check this you can pass the command form of the help call into which as text and which will tell you what function will be called:
which help('addme')
/MATLAB/toolbox/matlab/helptools/help.m
If MATLAB were going to call an object method, it would list that method.
x = sym('x'); % sym object
which plus(x, 1) % what gets called for x+1? The plus method for sym objects
/MATLAB/toolbox/symbolic/symbolic/@sym/plus.m % sym method

Hi @Kevin,
I was not able to reproduce the issue on my end, but I did notice that the issue you are facing could be caused by having two addme.m files with the one having the description being shadowed by the file not having it.
You can check which addme.m is being used by using the following command:
which -all addme
See if this helps you.
