Find inverse matrix using lu decomposition

WebMar 31, 2024 · A QR-decomposition can certainly be used for matrix inversion because if A = Q R then A − 1 = R − 1 Q − 1 = R − 1 Q T and R − 1 is easy to compute because R is triangular. But consider why you need to invert a matrix. In most cases, you don't: you just need to solve a linear system A x = b. If A = Q R then this system is equivalent to ... WebApr 5, 2024 · The LU decomposition of a matrix A can be written as: A = L U. Where, L = [ a b c 0 e f 0 0 i] And. L = [ a 0 0 d e 0 g h i] L = Lower Triangular Matrix. U = Upper Triangular Matrix. The lu factorization calculator with steps uses the above formula for the LU factorization of a matrix and to find the lu decomposition.
