Filter data with an infinite impulse response (IIR) or finite impulse response (FIR) filter

C++ Prototype

mwArray filter(const mwArray &b, const mwArray &a,
                const mwArray &X);
mwArray filter(mwArray *zf, const mwArray &b, const mwArray &a,
                const mwArray &X);
mwArray filter(const mwArray &b, const mwArray &a, const mwArray &X,
                const mwArray &zi);
mwArray filter(mwArray *zf, const mwArray &b, const mwArray &a,
                const mwArray &X, const mwArray &zi);
mwArray filter(const mwArray &b, const mwArray &a, const mwArray &X,
                const mwArray &zi, const mwArray &dim);
mwArray filter(mwArray *zf, const mwArray &b, const mwArray &a,
                const mwArray &X, const mwArray &zi,
                const mwArray &dim);

C++ Syntax

#include "matlab.hpp"

mwArray b, a, X, zi, dim;   // Input argument(s)
mwArray zf;                 // Output argument(s) 
mwArray y;                  // Return value

y = filter(b,a,X);
y = filter(&zf,b,a,X);
y = filter(b,a,X,zi);
y = filter(&zf,b,a,X,zi);
y = filter(b,a,X,zi,dim); 
y = filter(&zf,b,a,X,zi,dim); 
y = filter(b,a,X,empty(),dim); 
y = filter(&zf,b,a,X,empty(),dim); 

MATLAB Syntax

y = filter(b,a,X)
[y,zf] = filter(b,a,X)
[y,zf] = filter(b,a,X,zi)
y = filter(b,a,X,zi,dim)
[...] = filter(b,a,X,[],dim)
