S2GCSS

 
Vectorized solver, by cyclic reduction, for a block tridiagonal system that
arises from finite difference approximations to two-dimensional separable
elliptic partial differential equations with variable coefficients.
(Vectorized version of FISHPAK's BLKTRI).
 
Classes  :  I2b4b . Solution of discretized elliptic equations
 
Type     : Fortran subroutine in CRAYFISHPAK library.
Access   : Proprietary. Many implementations available.
Precision: Double.
Note     : Vectorized
 
Usage    : CALL S2GCSS (LDIMF, F, SAVE, W)
 
Details  : Documentation
Sites    : (1) ARNO
