## Detailed Description

## Function Documentation

## inv() [1/4]

ITPP_EXPORT bool itpp::inv | ( | const mat & | X,
|  | mat & | Y
| ) |  |

Inverse of real square matrix.

Calculate the inverse of the real matrix

Solves the equation system using LU-factorization. IT++ needs to be compiled with the LAPACK for the inverse to be available.
