Function Documentation

bool itpp::inv ( const mat X,
mat Y 
)

Inverse of real square matrix.

Calculate the inverse of the real matrix $\mathbf{X}$.

Solves the equation system $ \mathbf{Y} \mathbf{X} = \mathbf{I}$ using LU-factorization. IT++ needs to be compiled with the LAPACK for the inverse to be available.
