Solving linear systems matrix
WebMay 13, 2016 · I want to solve Ax = b where A is a very large square positive definite symmetric block matrix and x and b are vectors. When I say large I mean for a nxn matrix … Webx = A\B solves the system of linear equations A*x = B. The matrices A and B must have the same number of rows. MATLAB ® displays a warning message if A is badly scaled or nearly singular, but performs the calculation regardless. If A is a square n -by- n matrix and B is a matrix with n rows, then x = A\B is a solution to the equation A*x = B ...
