Constructor & Destructor Documentation

theplu::yat::utility::MatrixWeighted::MatrixWeighted

(

void

)

The default constructor.

Creates a zero size MatrixWeighted

theplu::yat::utility::MatrixWeighted::MatrixWeighted	(	size_t	r,
		size_t	c,
		double	init_value = 0,
		double	init_weight = 1.0
	)

Create a r times c MatrixWeighted.

If r is zero c must be zero and vice versa.

Constructor allocating memory space for r times c elements, and sets all elements to DataWeight(init_value, init_weight)

theplu::yat::utility::MatrixWeighted::MatrixWeighted ( const Matrix &  other )

explicit

Constructor.

Data is copied from other and weights are calculated using the binary_weight function, i.e., a NaN gets a zero weight (0.0) and other data values results in a unity weight (1.0).

theplu::yat::utility::MatrixWeighted::MatrixWeighted ( std::istream &  , char  sep = '\0'  )

explicit

The istream constructor.

This constructor first creates a Matrix using the Matrix istream constructor, and then constructs MatrixWeighted using MatrixWeighted(const Matrix&).

Note

Weights cannot be set from the streams. Weights are set as outlined in the MatrixWeighted(const Matrix&) documentation.

)

Returns

iterator pointing to end of matrix

const_iterator theplu::yat::utility::MatrixWeighted::end

(

void

)

const

Returns

size_t

i

)

Returns

iterator pointing to end of column i

const_column_iterator theplu::yat::utility::MatrixWeighted::end_column

(

size_t

i

)

const

Returns

const_iterator pointing to end of column i

row_iterator theplu::yat::utility::MatrixWeighted::end_row

(

size_t

i

)

Returns

iterator pointing to end of row i

const_row_iterator theplu::yat::utility::MatrixWeighted::end_row

(

size_t

i

)

const

Returns

const_iterator pointing to end of row i

DataWeight& theplu::yat::utility::MatrixWeighted::operator()	(	size_t	row,
		size_t	column
	)

Element access operator.

Returns

Reference to the element position (row, column).

const DataWeight& theplu::yat::utility::MatrixWeighted::operator()	(	size_t	row,
		size_t	column
	)		const

Element access operator.

Returns

Const reference to the element position (row, column).

const MatrixWeighted& theplu::yat::utility::MatrixWeighted::operator=

(

const MatrixWeighted &

other

)

The assignment operator.

Returns

A const reference to the resulting Matrix.

void theplu::yat::utility::MatrixWeighted::resize	(	size_t	rows,
		size_t	columns
	)

Resize MatrixWeighted.

Elements in MatrixWeighted are undefined after a resize.

If rows is zero columns must be zero and vice versa.

Note

this function may invalidate iterators.

size_t theplu::yat::utility::MatrixWeighted::rows

(

void

)

const

Returns

The number of rows in the matrix.

void theplu::yat::utility::MatrixWeighted::swap

(

MatrixWeighted &

other

)

swap objects

Takes constant time. Invalidates iterators. There is no requirement on the size of other.

Friends And Related Function Documentation

void swap ( MatrixWeighted &  , MatrixWeighted &    )

related

Exchange all elements.

Takes constant time.
