Description: A packages for solving large sparse linear systems by iterative methods.
to see the number of accesses to this library. # There are four packages in the ITPACK directory for solving # large sparse linear systems by iterative methods: ITPACK 2C (single # precision), ITPACK 2C (double precision), ITPACKV 2D (a vectorized # version of ITPACK 2C for the Cray Y-MP and similar vector computers), # and NSPCG. ITPACK 2C and ITPACKV 2D are intended for symmetric and # positive-definite matrix problems. NSPCG has preconditioners and # polynomial accelerators for nonsymmetric matrix problems as well. # Only single precision versions are available for ITPACKV 2D # and NSPCG. Machine-dependent constants and the timing function may # need to be modified by the user when installing the packages for a # particular computer. They are located in routines DFAULT and TIMER in # all four packages. file
