feval variable number of arguements

I use feval to evaluate user created functions. These user created functions have five arguements, so the call is [return args]=feval(function_name, arg1,arg2,arg3,arg4,arg5);

A new user created function now has a need for 8 input arguements. The question is:

Can MATLAB query the function_name to determine the number of arguements required before the feval call? Thanks, Bryan

Of course you can check the name of the function before calling using STRCMP.

In such cases it is often more preactical to define the input arguments as cell:

Inputs = {arg1,arg2,arg3,arg4,arg5};
feval(function_name, Inputs{:})

Or the equivalent method for 8 inputs.

Anyhow, I do not have the impression, that I got your problem completely.
