Detailed Description

template<typename _Scalar, int _Flags>
class Eigen::SparseMatrix< _Scalar, _Flags >

Sparse matrix.

Parameters:

_Scalar

the scalar type, i.e. the type of the coefficients

See http://www.netlib.org/linalg/html_templates/node91.html for details on the storage scheme.

Member Function Documentation

Scalar& fillrand	(	int	row,
		int	col
	)			[inline]

Like fill() but with random inner coordinates.

int nonZeros

(

)

const [inline]

Returns:

the number of non zero coefficients

void resize	(	int	rows,
		int	cols
	)			[inline]

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

See also:

resizeNonZeros(int), reserve(), setZero()

void startFill

(

int

reserveSize = 1000

)

[inline]

Initializes the filling process of *this.

Parameters:

reserveSize

approximate number of nonzeros Note that the matrix *this is zero-ed.
