Minimum norm solution to a linear system

Web2 Solving Optimization Problems by Plotting and Staring (10 points) 2.1 (5 points) Minimum-norm solutions to a linear system of equations Consider the following constrained … WebConsider the system of linear equations y = Hx: If there are many solutions, then the system is ‘underdetermined’. This frequently happens when H is a ‘wide’ matrix (more columns than rows) with linearly independent rows. In this case, it is common to seek a solution x with minimum norm. That is, we would like to solve the optimization ...
