Detailed Description

template<typename TStorage>
class ug::DenseMatrixInverse< TStorage >

smallInverse<size_t n> A class to hold a inverse of a smallMatrix<n> implemented with LAPACKs LU-Decomposition dgetrf (uses double[n*n] for LU and interchange[n] for pivoting

smallInverse<size_t n> A class to hold a inverse of a smallMatrix<n>
