Differences and approximate derivatives

C++ Prototype

mwArray diff(const mwArray &X);
mwArray diff(const mwArray &X, const mwArray &n);
mwArray diff(const mwArray &X, const mwArray &n, 
              const mwArray &dim);

C++ Syntax

#include "matlab.hpp"

mwArray X, n, dim;     // Input argument(s)
mwArray Y;             // Return value

Y = diff(X);
Y = diff(X,n);
Y = diff(X,n,dim);

MATLAB Syntax

Y = diff(X)
Y = diff(X,n)
Y = diff(X,n,dim)
