Non Negative Least Squares (NNLS)

On this page I have made available the source code for Lawson-Hanson's NNLS algorithm. I have hacked the version of nnls.c that i found at:
Sandia labs The versions below are in C++ and also attached is a sample file using a call to the subroutine nnls (note that arrays are column major because of fortran code)
  1. nnls.h Header file for NNLS
  2. nnls.cc Source code
  3. tmain.cc Sample source code
