# More work on Sparse Matrices

Hi All,

During this week I completed more functionalities regarding to CSR Matrices. I mainly implemented a generalized binary operation between two matrices. It’s similar to the SciPy function csr_binop_csr_canonical. This method applies a given binary function, to each corresponding elements of the two matrices which are given as input arguments, i.e. entry of the output matrix is equal to where and are the entries of input matrices respectively.

Also, I implemented methods for CSRMatrix class. It took me while to get this completely right as I was discarding some of the possible cases.

I originally planned to start writing python wrappers but I couldn’t do it as I was a bit busy with a project in my university. But I hope to get started on this in upcoming week. Although the GSoC is officially over, I will work on the project for two additional weeks as I took a two weeks break during the programme.
