Detailed Description

template<typename _Scalar, int _Options, typename _Index>
class SparseVector< _Scalar, _Options, _Index >

a sparse vector class

Template Parameters:
_Scalarthe 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.

This class can be extended with the help of the plugin mechanism described on the page Customizing/Extending Eigen by defining the preprocessor symbol EIGEN_SPARSEVECTOR_PLUGIN.

Scalar& SparseVector< _Scalar, _Options, _Index >::coeffRef ( Index  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.
