Detailed Description

template<class MatrixType>
class SparseBlockMatrixCCS< MatrixType >

Sparse matrix which uses blocks.

This class is used as a const view on a SparseBlockMatrix which allows a faster iteration over the elements of the matrix.

fillCCS()

template<class MatrixType>

int SparseBlockMatrixCCS< MatrixType >::fillCCS ( g_type * Cx, bool upperTriangle = false ) const

inline

fill the CCS arrays of a matrix, arrays have to be allocated beforehand.

This function only writes the values and assumes that column and row structures have already been written.
