Computes the inverse of a matrix

Description

Computes the inverse of a matrix using the LU decomposition.

Usage

solve2(A)

Arguments

A

an invertible square matrix.

Details

Use the LU decomposition to compute the inverse of a matrix. In some cases, solve produces error to invert a matrix whereas this decomposition provide a valid solution.

Value
