Lu decomposition calculator with steps
This calculator uses Wedderburn rank reduction to find the LU factorization of a matrix A A . The process constructs the two matrices L L and U U in stages. L L is constructed a column at a time while U U is constructed a row at a time. At each stage you'll have an equation A = LU + B A = L U + B where you start with L L and U U nonexistent and ...Description. The lu function expresses a matrix X as the product of two essentially triangular matrices, one of them a permutation of a lower triangular matrix and the other an upper triangular matrix. The factorization is often called the LU, or sometimes the LR, factorization. X can be rectangular.
