Functions
template<typename T >
bool	is_square (Matrix< T > const &data)
	Return whether a Matrix is a square matrix, that is, whether its number of rows and number of columns are idetical. More...
template<typename T >
bool	is_symmetric (Matrix< T > const &data)
	Return whether a Matrix is symmetric, i.e., whether it is square and m[ i, j ] == m[ j, i ] holds for all entries. More...
template<>
std::ostream &	operator<< (std::ostream &os, const Matrix< signed char > &matrix)
	Template specialization for signed char, in order to print nicely. More...
template<typename T >
std::ostream &	operator<< (std::ostream &os, const Matrix< T > &matrix)
	Print the elements of a Matrix to a stream, using operator << for each element. More...
template<>
std::ostream &	operator<< (std::ostream &os, const Matrix< unsigned char > &matrix)
	Template specialization for unsigned char, in order to print nicely. More...
template<typename T >
std::string	print (Matrix< T > const &matrix, size_t rows=10, size_t cols=10)
	Print a Matrix to a std::string. More...
template<typename T >
void	print (std::ostream &out, Matrix< T > const &matrix, size_t rows=10, size_t cols=10)
	Print a Matrix to an out stream. See print( Matrix<T> const&, size_t, size_t ) for details. More...
template<typename T >
void	swap_cols (Matrix< T > &data, size_t col_a, size_t col_b)
	Swap (interchange) two columns of a Matrix, given their indices. More...
template<typename T >
void	swap_rows (Matrix< T > &data, size_t row_a, size_t row_b)
	Swap (interchange) two rows of a Matrix, given their indices. More...
template<typename T >
Matrix< T >	transpose (Matrix< T > const &data)
	Transpose a Matrix. More...
size_t	triangular_index (size_t i, size_t j, size_t n)
	Given indices i and j in a quadratic Matrix, find the corresponding linear index. More...
std::pair< size_t, size_t >	triangular_indices (size_t k, size_t n)
	Given a linear index in a upper triangular Matrix, find the corresponding Matrix indices. More...
size_t	triangular_size (size_t n)
	Calculate the number of linear indices needed for a triangular Matrix of size n. More...
