Detailed Description

template<typename Derived>
class Eigen::SparseMatrixBase< Derived >

Base class of any sparse matrices or sparse expressions.

Template Parameters

Derived This class can be extended with the help of the plugin mechanism described on the page TopicCustomizingEigen by defining the preprocessor symbol EIGEN_SPARSEMATRIXBASE_PLUGIN.

Definition at line 26 of file SparseMatrixBase.h.

Member Typedef Documentation

template<typename Derived>

typedef NumTraits<Scalar>::Real Eigen::SparseMatrixBase< Derived >::RealScalar

This is the "real scalar" type; if the Scalar type is already real numbers (e.g. int, float or double) then RealScalar is just the same as Scalar. If Scalar is std::complex<T> then RealScalar is T.

See also: class NumTraits

Definition at line 118 of file SparseMatrixBase.h.

template<typename Derived>

typedef Matrix<Scalar,EIGEN_SIZE_MAX(RowsAtCompileTime,ColsAtCompileTime), EIGEN_SIZE_MAX(RowsAtCompileTime,ColsAtCompileTime)> Eigen::SparseMatrixBase< Derived >::SquareMatrixType

type of the equivalent square matrix

Definition at line 129 of file SparseMatrixBase.h.

Member Enumeration Documentation

template<typename Derived>

anonymous enum

Enumerator
RowsAtCompileTime	The number of rows at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. See also MatrixBase::rows(), MatrixBase::cols(), ColsAtCompileTime, SizeAtCompileTime
ColsAtCompileTime	The number of columns at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. See also MatrixBase::rows(), MatrixBase::cols(), RowsAtCompileTime, SizeAtCompileTime
SizeAtCompileTime	This is equal to the number of coefficients, i.e. the number of rows times the number of columns, or to Dynamic if this is not known at compile-time. See also RowsAtCompileTime, ColsAtCompileTime
IsVectorAtCompileTime	This is set to true if either the number of rows or the number of columns is known at compile-time to be equal to 1. Indeed, in that case, we are dealing with a column-vector (if there is only one column) or with a row-vector (if there is only one row).
Flags	This stores expression Flags flags which may or may not be inherited by new expressions constructed from this one. See the list of flags.
CoeffReadCost	This is a rough measure of how expensive it is to read one coefficient from this expression.

template<typename Derived>

template<typename CustomBinaryOp , typename OtherDerived >

EIGEN_STRONG_INLINE const CwiseBinaryOp<CustomBinaryOp, const Derived, const OtherDerived> Eigen::SparseMatrixBase< Derived >::binaryExpr	(	const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &	other,
		const CustomBinaryOp &	func = `CustomBinaryOp()`
	)		const

inline

Returns: an expression of the difference of *this and other

Note: If you want to substract a given scalar from all coefficients, see Cwise::operator-().

See also: class CwiseBinaryOp, operator-=()

Returns: an expression of the sum of *this and other

Note: If you want to add a given scalar to all coefficients, see Cwise::operator+().

See also: class CwiseBinaryOp, operator+=()

Returns: an expression of a custom coefficient-wise operator func of *this and other

The template parameter CustomBinaryOp is the type of the functor of the custom operator (see class CwiseBinaryOp for an example)

Here is an example illustrating the use of custom functors:

Output:

template<typename Derived>

Block<Derived> Eigen::SparseMatrixBase< Derived >::block	(	Index	startRow,
		Index	startCol,
		Index	blockRows,
		Index	blockCols
	)

inline

Returns: a dynamic-size expression of a block in *this.

Parameters

startRow	the first row in the block
startCol	the first column in the block
blockRows	the number of rows in the block
blockCols	the number of columns in the block

Example:

Output:

Note: Even though the returned expression has dynamic size, in the case when it is applied to a fixed-size matrix, it inherits a fixed maximal size, which means that evaluating it does not cause a dynamic memory allocation.

template<typename Derived>

const Block<const Derived> Eigen::SparseMatrixBase< Derived >::block	(	Index	startRow,
		Index	startCol,
		Index	blockRows,

inline

This is the const version of block(Index,Index,Index,Index).

template<typename Derived>

template<int BlockRows, int BlockCols>

Block<Derived, BlockRows, BlockCols> Eigen::SparseMatrixBase< Derived >::block	(	Index	startRow,
		Index	startCol
	)

inline

Returns: a fixed-size expression of a block in *this.

The template parameters BlockRows and BlockCols are the number of rows and columns in the block.

Parameters

startRow	the first row in the block
startCol	the first column in the block

Example:

Output:

Note: since block is a templated member, the keyword template has to be used if the matrix type is also a template parameter:
m.template block<3,3>(1,1);

Block<Derived, BlockRows, BlockCols> Eigen::SparseMatrixBase< Derived >::block	(	Index	startRow,
		Index	startCol,
		Index	blockRows,
		Index	blockCols
	)

inline

Returns: an expression of a block in *this.

Template Parameters

BlockRows	number of rows in block as specified at compile time
BlockCols	number of columns in block as specified at compile time

Parameters

startRow	the first row in the block
startCol	the first column in the block
blockRows	number of rows in block as specified at run time
blockCols	number of columns in block as specified at run time

This function is mainly useful for blocks where the number of rows is specified at compile time and the number of columns is specified at run time, or vice versa. The compile-time and run-time information should not contradict. In other words, blockRows should equal BlockRows unless BlockRows is Dynamic, and the same for the number of columns.

Block<Derived, CRows, CCols> Eigen::SparseMatrixBase< Derived >::bottomLeftCorner	(	Index	cRows,

inline

Returns: an expression of a bottom-left corner of *this.

Template Parameters

CRows	number of rows in corner as specified at compile time
CCols	number of columns in corner as specified at compile time

Parameters

cRows	number of rows in corner as specified at run time
cCols	number of columns in corner as specified at run time

This function is mainly useful for corners where the number of rows is specified at compile time and the number of columns is specified at run time, or vice versa. The compile-time and run-time information should not contradict. In other words, cRows should equal CRows unless CRows is Dynamic, and the same for the number of columns.

Block<Derived, CRows, CCols> Eigen::SparseMatrixBase< Derived >::topLeftCorner	(	Index	cRows,

	)

inline

Returns: an expression of a top-left corner of *this.

Template Parameters

CRows	number of rows in corner as specified at compile time
CCols	number of columns in corner as specified at compile time

Parameters

cRows	number of rows in corner as specified at run time
cCols	number of columns in corner as specified at run time

This function is mainly useful for corners where the number of rows is specified at compile time and the number of columns is specified at run time, or vice versa. The compile-time and run-time information should not contradict. In other words, cRows should equal CRows unless CRows is Dynamic, and the same for the number of columns.
