avoiding global variables was the reason why I used function handles in the
first place.
using function handles you can construct a function whith just one input
parameter
from one with multiple parameters like this:
## fun is a function that takes two inputs
function f = fun (x, p)
f = x + p;
endfunction
## fix the value of p
p = 3;
## specialized_fun is a function of x only
specialized_fun = @(x) fun (x, p)
## fix a different value of p
p = 2;
## specialized_fun_2 is also a function of x
## but is different from specialized_fun
specialized_fun_2 = @(x) fun (x, p)
The rough C++ equivalent of this is something like
#include <iostream>
class fun
{
private:
const double p;
public:
fun (const double pin) : p (pin) {};
double operator() (const double x) {return (x+p);};
};
int main (void)
{
fun specialized_fun (3.0);
std::cout << specialized_fun (1.0) << std::endl;
fun specialized_fun_2 (2.0);
std::cout << specialized_fun_2 (1.0) << std::endl;
}
