<A HREF="../Mat/MATAIJCUSP.html#MATAIJCUSP">MATAIJCUSP</A> = "aijcusp" = "seqaijcusp" - A matrix type to be used for sparse matrices. A matrix type type whose data resides on Nvidia GPUs. These matrices are in CSR format by
default. All matrix calculations are performed using the CUSP library.
DIA and ELL formats are ONLY available when using the 'txpetscgpu' package.
Use --download-txpetscgpu to build/install PETSc to use different GPU storage formats
with CUSP matrix types.
