WebApr 22, 2024 · 7. For example, for matrix A, B, I know that when I use LinearSolve [A,B] that means it will solve for x which fulfill Ax=B. However, what if xA=B case. I was trying to inverse A and B and make B^-1x=A^-1 but the A is not invertible so how I solve is.. Solve [ { {x1 + x2 + x3, 5 x1 + 6 x2 + 11 x3}, {y1 + y2 + y3, 5 y1 + 6 y2 + 11 y3}} == { {1 ... 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.
WebDec 22, 2024 · For algorithms that solve AX=B in least squares sense the value returned for X is such that the residual AX-B has minimal norm. Least Square sense means a solver can be computed for an overdetermined system, (i.e. a system with more equations than unknowns, which corresponds to a tall A matrix with more rows than columns). WebDec 9, 2024 · x = A \ b is the general formulation that should be efficient in most cases.. If you know that A is Hermitian and positive definite, then x = cholesky(A) \ b is probably better.. If you have a fast way of computing the matrix-vector product A*x, then have a look at IterativeSolvers.jl.. You should almost never use x = inv(A) * b.If you need to re-solve …
