nnls-package {nnls} | R Documentation |
An R interface to the NNLS algorithm for non-negative least squares that solves the least squares problem Ax = b with the constraint x >=q 0 where where x in R^n, b in R^m and A is an m times n matrix. Also allows the combination of non-negative and non-positive constraints on x.
