Matrix inverse
Calculates the inverse of a square matrix.
Inverse of a matrix
The inverse of a square matrix `A` is the matrix noted `A^(-1)` such as,
`A*A^(-1) = I`
where `I` is the identity matrix.
The inverse matrix of A exists if and only if the determinant of A is non-zero. We say that M is invertible or not singular.
