S.K. Sen, Sagar Sen · Journal of Computational Methods in Sciences and Engineering · 2006
Presented here is an O(mn2 ) physically concise algorithm (solver) to obtain noniteratively a minimum-norm (m-) solution of the consistent under-/over-determined linear system Ax=b without computing any generalized inverse (g-inverse), where the matr
