WebOct 21, 2013 · Use LSQR to solve the system A*dx = r0. Add the correction dx to obtain a final solution x = x0 + dx. This requires that x0 be available before and after the call to LSQR. To judge the benefits, suppose LSQR takes k1 iterations to solve A*x = b and k2 iterations to solve A*dx = r0. If x0 is “good”, norm (r0) will be smaller than norm (b).
