Template Class matrix_expression

Class Documentation

template<typename M>
class matrix_expression

Base for the matrix expression templates This all uses the Curiously recurring template pattern.

Template Parameters:

M – The type of the derived class

Public Functions

inline std::size_t dim_m() const

Return the size (dimension) in direction m.

inline std::size_t dim_n() const

Return the size (dimension) in direction n.

inline bool empty() const

Convenient way to test for empty matrices.

inline auto &operator()(std::size_t i, std::size_t j)

Return a reference to element [ i, j ]

inline auto operator()(std::size_t i, std::size_t j) const

Return the value of element [ i, j ]

inline void swap_row(std::size_t r1, std::size_t r2)

Swap the contents of rows r1 and r2

inline void swap_col(std::size_t c1, std::size_t c2)

Swap the contents of columns c1 and c2

template<typename M2>
inline bool operator==(const matrix_expression<M2> &m) const

compare two matrices

Friends

inline friend std::ostream &operator<<(std::ostream &os, const matrix_expression &m)

write the matrix m to std::ostream os
