Detailed Description

template<typename _Scalar, int _Flags = 0>
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.

Constructor & Destructor Documentation

~SparseMatrix ( )

inline

Destructor

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.
