Detailed Description

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

a sparse vector class

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& coeffRef

(

int

i

)

[inline]

Returns:

a reference to the coefficient value at given index i This operation involes a log(rho*size) binary search. If the coefficient does not exist yet, then a sorted insertion into a sequential buffer is performed.

This insertion might be very costly if the number of nonzeros above i is large.

Scalar& fillrand

(

int

i

)

[inline]

Like fill() but with random coordinates.

int nonZeros

(

)

const [inline]

Returns:

the number of non zero coefficients
