Sparse Matrix Multiplication

Sparse Matrix Multiplication

Hey all I am working on very big size of matrix which have more zeros value compare to non zeroes value(Sparse Matrix). I want to do multiplication of this two sparse matrix so is there any function for Sparse Matrix multiplication. Now i m using mkl_?csrmm to do multiplication but in  this only i can take one sparse matrix and other is dense matrix. so please let me know how to do this task. if any alternative is available please tell that also.

Please look at mkl_scsrmultcsr(..) which computes product of two sparce matrixes stored in the CSR format.
