In this section, we review how sparse matrices are stored internally,
at the library level.
As we are going to see, the format used in Scilab is very similar to the compressed sparse
As we are going to see, the format used in Scilab is very similar (but not
exactly identical) to the compressed sparse
row format (CSR), in which the nonzero entries are stored row-by-row.
While this detail does not change the way a user user sparse matrices at the
interpreter level, it does have an impact on the way the libraries are

This current storage is different from the CSR format, in the sense that
there is no array containing the row indices corresponding to the values and
no array containing the cumulated indexes where each column starts.
