3.4. Given A e RmxN, suppose that every m x m submatrix of A is invertible. For x E RN, let x# be the unique minimizer of ||2||1 subject to Az = Ax. Prove that either x = x or supp(x) & supp(xF). 3.4. Given A e RmxN, suppose that every m x m submatrix of A is invertible. For x E RN, let x# be the unique minimizer of ||2||1 subject to Az = Ax.
