WebGenerally, COO is easiest to work with if you are writing human-readable code ;) and will almost always be faster if you have a super-sparse matrix. CSR (Or CSC depending on your linear algebra package/implementation) is generally faster - meaning for a random sparse matrix. There are other more specialized forms of compression that can do ... WebAs illustrated below, the COO format may also be used to efficiently construct matrices. To perform manipulations such as multiplication or inversion, first convert the matrix to either CSC or CSR format. The lil_matrix format is row-based, so conversion to CSR is efficient, whereas conversion to CSC is less so.
