There are two fixed size matrix types, but unfortunately they are
not documented:
template<class T, std::size_t M, std::size_t N, class L = row_major>
class bounded_matrix;
template<class T, std::size_t M, std::size_t N>
class c_matrix;
Both are defined in matrix.hpp.
bounded_matrix uses bounded_array for storage:
template<class T, std::size_t M, std::size_t N, class L>
class bounded_matrix:
public matrix<T, L, bounded_array<T, M * N> > { /* ... */ };
Therefore it can have row major and column major storage.
c_matrix wraps C array:
template<class T, std::size_t N, std::size_t M>
class c_matrix {
// ...
T data_ [N] [M];
};
Obviously, it must be row major.
