DSRC2C

 
ITPACK 2C: Subroutines for solving large sparse linear systems by adaptive
accelerated iterative methods. Can be called with any system with positive
diagonal elements, but are best applied for systems with symmetric positive
definite coefficient matrices. Routines for conjugate gradient or Chebyshev
acceleration applied to the Jacobi, SSOR, or Reduced System iterative methods
are supplied. Uses the A-IA-JA sparse matrix format.
 
Classes  :  D2b4 . Solution of systems of linear equations, including matrix
                 inverses, and LU and related factorizations (real symmetric
                 sparse matrices)
 
Type     : Fortran subroutine in ITPACK package.
Access   : Public domain. Portable.
Precision: Double.
