Detailed Description
template<class T, unsigned int N>
class vnl_diag_matrix_fixed< T, N >
stores a diagonal matrix as a single vector.
vnl_diag_matrix_fixed stores a diagonal matrix for time and space efficiency. Specifically, only the diagonal elements are stored, and some matrix operations (currently *, + and -) are overloaded to use more efficient algorithms.
