S2CFSS

 
Vectorized solver, by FFTs, for a block tridiagonal system that arises from
finite difference approximations on a staggered grid to two-dimensional
separable elliptic partial differential equations with constant coefficients
in one direction.
 
Classes  :  I2b4b . Solution of discretized elliptic equations
 
Type     : Fortran subroutine in CRAYFISHPAK library.
Access   : Proprietary. Many implementations available.
Precision: Double.
Note     : Vectorized
 
Usage    : CALL S2CFSS (LDIMF, F, SAVE, W)
 
Details  : Documentation
Sites    : (1) ARNO
