nnls

Nonnegative least squares

Note    The nnls routine was replaced by lsqnonneg in Release 11 (MATLAB 5.3). In Release 12 (MATLAB 6.0), nnls displays a warning and calls lsqnonneg.

C++ Prototype

mwArray nnls(const mwArray &A, const mwArray &b);
mwArray nnls(const mwArray &A, const mwArray &b,
              const mwArray &tol);
mwArray nnls(mwArray *w, const mwArray &A, const mwArray &b);
mwArray nnls(mwArray *w, const mwArray &A, const mwArray &b,
              const mwArray &tol);

C++ Syntax

#include "matlab.hpp"

mwArray A, b, tol;     // Input argument(s)
mwArray w;             // Output argument(s) 
mwArray x;             // Return value

x = nnls(A,b);
x = nnls(A,b,tol);
x = nnls(&w,A,b);
x = nnls(&w,A,b,tol);

MATLAB Syntax

x = nnls(A,b)
x = nnls(A,b,tol)
[x,w] = nnls(A,b)
[x,w] = nnls(A,b,tol)
