Function evaluation

C++ Prototype

mwArray feval(mwVarargout vout, 
               mlxFunctionPtr fcn, /* ptr to a function */
               const mwVarargin &in1,
               const mwArray &in2=mwArray::DIN,
               .
               .
               .
               const mwArray &in32=mwArray::DIN);

mwArray feval(mwVarargout vout, 
               const mwArray &fcn, /* function name as string */
               const mwVarargin &in1, 
               const mwArray &in2=mwArray::DIN,
               .
               .
               .
               const mwArray &in32=mwArray::DIN);

C++ Syntax

#include "matlab.hpp"

mwArray fcn,x1;             // Input argument(s)
mwArray y2;                 // Output argument(s) 
mwArray y1;                 // Return value

y1 = feval(fcn);
y1 = feval(fcn,x1);
y1 = feval(&y2,fcn,x1,...);
y1 = feval("func");
y1 = feval("func",x1);
y1 = feval(&y2,"func",x1,...);

MATLAB Syntax

[y1,y2, ...] = feval(function,x1,...)
