POISTG

 
Solves block tridiagonal linear systems of algebraic equations arising from the
discretization of separable elliptic partial differential equations.
 
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 CMLIB library (FISHPAK sublibrary).
