Member Function Documentation

template<class MT>

TVector<MT> TSymMatrix< MT >::Col ( int c ) const

inlinevirtual

Returns a vector containing a copy of column 'c'.

Parameters

c	column index (>= 0)

Returns: vector containing column c

Note: Sparse matrix types expand to a dense column, with missing entries filled with zeros, so this can be used as a "scatter" operation.

See Also: Row

Implements TMatrix< MT >.

template<class MT>

MT TSymMatrix< MT >::Get	(	int	r,
		int	c
	)		const

inlinevirtual

Retrieve a matrix element.

Parameters

r	matrix row (0 <= r < nRows())
c	matrix column (0 <= c < nCols())

Returns: matrix element (*this)_r,c

Note: This is a read operation and returns the element value. For writing operations, use Put() or operator().

See Also: operator()

Implements TMatrix< MT >.

Referenced by Line2D2::BndIntPFF(), Line2D2::IntFDD(), and Line2D2::IntPDD().

template<class MT>

void TSymMatrix< MT >::New	(	int	nrows,
		int	ncols
	)

inlinevirtual

Resize and reset the matrix.

Resets the logical size of the matrix to nrows x ncols. Derived classes reallocate the data block and any index arrays, and reset the matrix elements to zero.

Parameters

nrows	new number of matrix rows
ncols	new number of matrix columns

Reimplemented from TMatrix< MT >.

template<class MT>

TVector<MT> TSymMatrix< MT >::Row ( int r ) const

virtual

Returns a vector containing a copy of row `r'.

Parameters

r	row index (>= 0)

Returns: vector containing row r

Note: Sparse matrix types expand to a dense row, with missing entries filled with zeros, so this can be used as a "scatter" operation.

See Also: SparseRow, SetRow

Implements TMatrix< MT >.

Referenced by TSymMatrix< double >::Col().

template<class MT>

int TSymMatrix< MT >::SparseRow	(	int	r,
		idxtype *	colidx,
		MT *	val
	)		const

virtual

Returns a row of the matrix in sparse format.

Returns a list of column indices and values for all allocated entries of row r. This is only really useful for sparse matrix types. For dense matrices this simply returns the complete row, with indices 0, 1, 2, ... n-1

Parameters

r	row index (>= 0)
colidx	pointer to array of column indices
val	pointer to array of element values

Returns: Actual number of allocated matrix entries in the row.

Note: The arrays must be allocated by the caller and be of sufficient size.

See Also: Row, SetRow

Implements TMatrix< MT >.

template<class MT>

MatrixStorage TSymMatrix< MT >::StorageType ( ) const

inlinevirtual

Matrix storage class.

Returns: storage class identifier
