Detailed Description

template<class ValueType>
class GIMLI::SparseMatrix< ValueType >

Sparse matrix in compressed row storage (CRS) form.

Sparse matrix in compressed row storage (CRS) form. IF you need native CCS format you need to transpose CRS Symmetry type: 0 = nonsymmetric, -1 symmetric lower part, 1 symmetric upper part.
