Detailed Description

template<unsigned int idim, unsigned int n = idim>
class Invert< idim, n >

Invert. Class to specialize calls to Dinv. Dinv computes the inverse of a square matrix if dimension $idim$ and order $n$. The content of the matrix will be replaced by its inverse. In case the inversion fails, the matrix content is destroyed. Invert specializes Dinv by the matrix order. E.g. if the order of the matrix is two, the routine Invert<2> is called which implements Cramers rule.
