Minimum norm solution to a linear system
Did you know?
WebThe solution computed by lsqminnorm minimizes not only norm(A*x-b), but also norm(x). Consider a simple linear system with one equation and two unknowns, 2 x 1 + 3 x 2 = 8. … WebNow, solve the linear system by providing minres with the function handle that calculates A*x. Use a tolerance of 1e-12 and 50 iterations. b = ones (21,1); tol = 1e-12; maxit = 50; x1 = minres (@afun,b,tol,maxit) minres converged at iteration 11 to a solution with relative residual 4.1e-16.
