Sparse Matrix Calculation Examples

ssylee — Wed, 04 Feb 2009 19:15:26 GMT

I am fully aware in the examples\spblas directory, there is a few c example files of using the Sparse BLAS routines. However, I have trouble understanding what the examples are doing. Would I need to familiarize myself with how sparse matrices are stored? If I am trying to perform a simple sparse matrix calculation of K and f, with K being a m x m matrix, and f being a m x 1 matrix, both of which are sparse, which example and documentation would you recommend to be the best starting point?

Thanks in advance.

Hi,
you can get the answer about how sparce matrix are stored from the name of the files:
For example
cspblas_dcsr.c - where "csr" means that matrices represented in the compressed sparse row storage scheme.
cspblas_sbsr.c the block compressed sparse row storage scheme
cspblas_scoo.c the coordinate storage scheme.
cspblas_scsc.c the compressed sparse column storage scheme
and etc

All info about Sparse Matrix Storage Formats you can find into MKL Reference Manual ( see in the Appendix A )".
