Hello,
I am currently facing the problem that I would like to apply the nargin/nargout function to a mex function I generated.
Usually one can use them in order get the number of inputs/outputs from outside the function. This works for example as follows:
>>nargin(@sum)
>>nargout(@sum)
When I use these functions on a generated mex function i get the following error:
>> Error using nargout
>> xyz_coder_mex does not know how to answer nargin/nargout.
Does anyone know a workaround or is it generally not possible to access these parameters of a mex function?
Greetings, Stefan

I found a workaround:
One can program a wrapper function, which is calling the mex function
e.q.
-----
function [a,b,c] = xyz_coder_wrapper(d,e,f)
[a,b,c] = xyz_coder_mex(d,e,f)
-----
Thereby one can use its knowledge of the underlying MATLAB/c function

Not sure why this question slipped through unnoticed. I've created an enhancement request to make nargin and nargout work when given a function handle to a MATLAB Coder generated mex file.
