Detailed Description

template<typename _Scalar, int _Options, typename _Index>
class Eigen::DynamicSparseMatrix< _Scalar, _Options, _Index >

A sparse matrix class designed for matrix assembly purpose.

Deprecated:
use a SparseMatrix in an uncompressed mode
Parameters:
_Scalarthe scalar type, i.e. the type of the coefficients

Unlike SparseMatrix, this class provides a much higher degree of flexibility. In particular, it allows random read/write accesses in log(rho*outer_size) where rho is the probability that a coefficient is nonzero and outer_size is the number of columns if the matrix is column-major and the number of rows otherwise.

Internally, the data are stored as a std::vector of compressed vector. The performances of random writes might decrease as the number of nonzeros per inner-vector increase. In practice, we observed very good performance till about 100 nonzeros/vector, and the performance remains relatively good till 500 nonzeros/vectors.

the coefficient value at given position row, col This operation involes a log(rho*outer_size) binary search.

Returns:
a reference to the coefficient value at given position row, col This operation involes a log(rho*outer_size) binary search. If the coefficient does not exist yet, then a sorted insertion into a sequential buffer is performed.

EIGEN_DEPRECATED Scalar& Eigen::DynamicSparseMatrix< _Scalar, _Options, _Index >::fill ( Index  row,

Deprecated:
use insert() inserts a nonzero coefficient at given coordinates row, col and returns its reference assuming that: 1 - the coefficient does not exist yet 2 - this the coefficient with greater inner coordinate for the given outer coordinate. In other words, assuming *this is column-major, then there must not exists any nonzero coefficient of coordinates i x col such that i >= row. Otherwise the matrix is invalid.
