how do I find where a function is defined (equivalent of "which" command in bash)

When I start Matlab on one of my work machines, I get the message:
"Warning: Function count has the same name as a MATLAB builtin.."
I know exactly what the message means, but I do not know how to fix it, because I can not find where I have defined the function "count". If this was in a bash shell I would type the command "which count". Is there a Matlab equivalent, which shows me where the function "count" has been redefined?

Yes, there is a which command in MATLAB. Note that count is an overloaded function, meaning it exists in several toolboxes. Here are the results in R2021a.
which -all count

Yes, the user will always see that message on startup.
C:\Program Files\MATLAB\R2020a\toolbox\local\count.m
What is the point of that? It is shadowed with the current path settings, so it will not be invoked -- the strfun\count version will be invoked for datatypes other than the ones listed as having @ .
If the intent is to have it be active only for a particular data type, you should build it into the class for that datatype.
