Detailed Description

template<typename ValueType = double>
struct skylark::base::sparse_matrix_t< ValueType >

This implements a very crude CSC sparse matrix container only intended to hold local sparse matrices.

Row indices are not sorted. Structure is always constants, and can only be attached by Attached. Values of non-zeros can be modified.
