Purpose Compute the inverse of a square matrix using LU factorization.

Library Math Functions / Matrices and Linear Algebra / Matrix Inverses

Description The LU Inverse block computes the inverse of the square input matrix A by

factoring and inverting row-pivoted variant A

L is a lower-triangular square matrix with unity diagonal elements, and U is

an upper-triangular square matrix. The block’s output is A

-1

, and is always

sample-based.
