WebJan 19, 2010 · Surely then it’s worthwhile to find A-1. No. The first time you solve Ax = b, you factor A and save that factorization. Then when you solve for the next b, the answer comes much faster. (Factorization takes O ( n3) operations. But once the matrix is factored, solving Ax = b takes only O ( n2) operations. Suppose n = 1,000. WebBeing able to augment and row-reduce is as good as being able to solve Ax=b, but maybe you prefer to have Sage give you the solution directly: M.solve_right(vector([7,13])) or b = vector([7,13]) M.solve_right(b) Let’s check it’s a solution: x = M.solve_right(b) M*x M*x==vector([7,13]) If you just use M.solve, though, you will get the wrong ...
