Gradient-descent iterative algorithm for solving exact and weighted least-squares solutions of rectangular linear systems

Consider a linear system Ax=b where the coefficient matrix A is rectangular and of full-column rank. We propose an iterative algorithm for solving this linear system, based on gradient-descent optimization technique, aiming to produce a sequence of well-approximate least-squares solutions. Here, we...
