Now, the following facts can be observed: Inverse of a lower triangular matrix L is again a lower triangular matrix. The multiplication of two lower triangular matrices is again a lower triangular matrix. It can be said that, L is a lower triangular matrix. So, it can be written that: Finally, we obtain: A = LU.

For sparse inputs, inv (X) creates a sparse identity matrix and uses backslash, X\speye (size (X)). The LU Inverse block computes the inverse of the square input matrix A by factoring and inverting row-pivoted variant A p. A p − 1 = ( L U ) − 1 L is a lower triangular square matrix with unity diagonal elements, and U is an upper triangular square matrix. Easy way to calculate inverse of an LU decomposition. I have a matrix A and a lower triangular matrix L (with 1's along the diagonal) and an upper triangular matrix U. These are constructed such that A = L U. I know that A − 1 = L − 1 U − 1 and I know that the inverse of … The LU Inverse block computes the inverse of the square input matrix A by factoring and inverting row-pivoted variant A p. A p − 1 = ( L U ) − 1 L is a lower triangular square … Compute the LU factorization of a matrix and examine the resulting factors.
