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. WebCreate a function to solve the system AX = B, for A, X, and B, n x n matrices. The function should take as input matrices A and B and give the output X. Validate your code. Explain how you validated and provide any relevant output.
