Detailed Description

template<class T>
class RowMatrix< T >

This class represents a generally non-symmetric dense matrix. It is an encapsulation of the cArray class with some operators bundled to it.

void RowMatrix< T >::plot_abs ( std::ofstream & out ) const

inline

This will write PNG file data to a supplied stream. The data written are the gray-scale representation of the absolute values of the dense matrix entries.

Note: This function uses PNG++ and can be disables if the macro NO_PNG is defined.

template<class Function >

void RowMatrix< T >::populate ( Function f )

inline

This method accepts a function object that is called for every matrix element. Use functions with signature

double (*) (int i, int j);

template<class T>

ArrayView<Type> RowMatrix< T >::row ( int i )

inline

Return shallow copy of a matrix row.

template<class T>

const ArrayView<Type> RowMatrix< T >::row ( int i ) const

inline

template<class T>

ColMatrix<Type> RowMatrix< T >::T ( ) const

inline

Return transposed matrix. The result is of the type ColMatrix, so that no reordering of the entries is necessary.

template<class T>

template<class Function >

void RowMatrix< T >::transform ( Function f )

inline

This method accepts a function object that is called for every matrix element. Use functions with signature

void (*) (int i, int j, T& x);

template<class T>

void RowMatrix< T >::write	(	std::ostream &	out,
		std::string const &	pre = `""`,
		std::string const &	pos = `""`
	)		const

inline

Write matrix to a text file. The format is influenced by the "pre" and "pos" characters supplied to the routine. The "pre" string will be present on the beginning of every row of the matrix, the "pos" string on the end. For example, the call

*     RowMatrix (
*         2, 2, rArray({1., 2., -2., 1.})
*     ).write (std::cout, "[", "]")
* 

will result in the following output to the STDOUT:

*     [ 1 2 ]
*     [-2 1 ]
*
