Description: Correlation algorithm based on a comparison of block pivoting and interior-point algorithms for linear least squares problems with nonnegative variables written. Contains: active-set, principal pivoting algorithms, Newton' s algorithm, predictor-corrector algorithm for solving the non-negative least squares problem is very practical, notes simple and easy to operate.
