In order to pass a function handle into your function, you must first register your function in the function look-up table. This is discussed in the C++ Math Library Users Guide.
Here is a simple example code that illustrates how to add the function "func" to the function table look-up.
#include "matlab.hpp"
mwArray func(mwArray x) /*Function that will be passed as a handle to another function*/
{
return sin(x);
}
DECLARE_FEVAL_TABLE /*Macro that adds the function func into the FEVAL table*/
FEVAL_ENTRY(func)
END_FEVAL_TABLE
int main(void)
{
mwArray x;
mwArray x0(2);
cout<<x0<<"\n"<<"\n"<<endl;
x = fzero("func",x0); /*func is passed to the function FZERO as a function handle*/
cout<<x<<endl;
return 0;
}
