The most efficient way to build up the structure is the COO format. So I
would advise to use the coordinate_matrix. One the structure is filled
you might want to create a compressed-sparse-column (or
compressed_matrix) matrix from the coordinate_matrix because operations
on the CSC are faster than one the COO.
