signature

Parse function argument names from an mfile or anonymous function handle

Returns a listing of function argument names

ARGSOUT = SIGNATURE.ARGOUT(FUN) returns a list of output arguments in the mfile corresponding to FUN

ARGSIN = SIGNATURE.ARGIN(FUN) returns a list of input arguments in the mfile corresponding to FUN

The latter also works for anonymous functions. For example:

signature.argin(@(x,y,z) z+y+x)
ans =
'x' 'y' 'z'
