<A HREF="../Mat/MATAIJCUSPARSE.html#MATAIJCUSPARSE">MATAIJCUSPARSE</A> = "(seq)aijcusparse" - A matrix type to be used for sparse matrices. A matrix type type whose data resides on Nvidia GPUs. These matrices can be in either
CSR, ELL, or Hybrid format. All matrix calculations are performed on Nvidia GPUs using
the CUSPARSE library. This type is only available when using the 'txpetscgpu' package.
Use --download-txpetscgpu to build/install PETSc to use different CUSPARSE library and
the different GPU storage formats.
