Eigen::SkylineMatrix< _Scalar, _Options > Class Template Reference

Detailed Description

template<typename _Scalar, int _Options>
class Eigen::SkylineMatrix< _Scalar, _Options >

The main skyline matrix class.

This class implements a skyline matrix using the very uncommon storage scheme.

Parameters:

_Scalar	the scalar type, i.e. the type of the coefficients
_Options	Union of bit flags controlling the storage scheme. Currently the only possibility is RowMajor. The default is 0 which means column-major.

Member Function Documentation

template<typename _Scalar , int _Options>

Index Eigen::SkylineMatrix< _Scalar, _Options >::cols

(

)

const [inline]

Returns:

the number of columns.

See also:

rows(), ColsAtCompileTime

Reimplemented from Eigen::SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >.

template<typename _Scalar , int _Options>

void Eigen::SkylineMatrix< _Scalar, _Options >::finalize

(

)

[inline]

Must be called after inserting a set of non zero entries.

template<typename _Scalar , int _Options>

Index Eigen::SkylineMatrix< _Scalar, _Options >::innerSize

(

)

const [inline]

Returns:

the size of the inner dimension according to the storage order, i.e., the number of rows for a columns major matrix, and the number of cols otherwise

Reimplemented from Eigen::SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >.

template<typename _Scalar , int _Options>

EIGEN_DONT_INLINE Scalar& Eigen::SkylineMatrix< _Scalar, _Options >::insert	(	Index	row,
		Index	col
	)		[inline]

Returns:

a reference to a novel non zero coefficient with coordinates row x col.

Warning:

This function can be extremely slow if the non zero coefficients are not inserted in a coherent order.

After an insertion session, you should call the finalize() function.

template<typename _Scalar , int _Options>

Index Eigen::SkylineMatrix< _Scalar, _Options >::nonZeros

(

)

const [inline]

Returns:

the number of non zero coefficients

Reimplemented from Eigen::SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >.

template<typename _Scalar , int _Options>

Index Eigen::SkylineMatrix< _Scalar, _Options >::outerSize

(

)

const [inline]

Returns:

the size of the storage major dimension, i.e., the number of columns for a columns major matrix, and the number of rows otherwise

Reimplemented from Eigen::SkylineMatrixBase< SkylineMatrix< _Scalar, _Options > >.

template<typename _Scalar , int _Options>

void Eigen::SkylineMatrix< _Scalar, _Options >::reserve	(	Index	reserveSize,
		Index	reserveUpperSize,
		Index	reserveLowerSize
	)		[inline]

Preallocates reserveSize non zeros

template<typename _Scalar , int _Options>

void Eigen::SkylineMatrix< _Scalar, _Options >::resize	(	size_t	rows,
		size_t	cols
	)		[inline]

Resizes the matrix to a rows x cols matrix and initializes it to zero

template<typename _Scalar , int _Options>

Index Eigen::SkylineMatrix< _Scalar, _Options >::rows

(

)

const [inline]

Returns:

the number of rows.
