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.
