    Sparse Matrices

    donpellegrino

      Given an AMD on 64-bit Linux environment what is the best way to work with sparse matrices?  I hunted through the AMD Core Math Library but I didn't see support for a sparse matrix.  I found the documentation for "3 BLAS: Basic Linear Algebra Subprograms" at http://developer.amd.com/cpu/Libraries/acml/onlinehelp/Documents/BLAS.html#index-sparse-BLAS-47 which reads:

      "ACML also includes interfaces to the extensions to Level 1 BLAS known as the sparse BLAS. These routines perform operations on a sparse vector x which is stored in compressed form and a vector y in full storage form. See reference [4] for more information."

      So it would seem that ACML supports sparse vectors but not sparse matrices.  If this is the case can someone recommend an alternative library?
