POIS3D

 
Solve a three-dimensional block tridiagonal linear system which arises from a
finite difference approximation to a three-dimensional Poisson equation using
the Fourier transform package FFTPAK written by Paul Swarztrauber.
 
Classes  :  D2a4 .  Solution of systems of linear equations, including matrix
                  inverses, and LU and related factorizations (real
                  nonsymmetric sparse matrices)
            I2b4b . Solution of discretized elliptic equations
 
Type     : Fortran subroutine in SLATEC library.
