Compute inverse of square matrix using LU factorization
The LU Inverse block computes the inverse of the square input matrix A by factoring and inverting row-pivoted variant Ap.
L is a lower triangular square matrix with unity diagonal elements, and U is an upper triangular square matrix. The block outputs the inverse matrix A-1.
See Find the Inverse of a Matrix Using the LU Inverse Block in the DSP System Toolbox™ User's Guide.
