PCGBTRS - solve a system of linear equations A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)

Name

       PCGBTRS - solve a system of linear equations   A(1:N, JA:JA+N-1) * X = B(IB:IB+N-1, 1:NRHS)

Purpose

       PCGBTRS solves a system of linear equations
                                         or
                 A(1:N, JA:JA+N-1)' * X = B(IB:IB+N-1, 1:NRHS)

       where A(1:N, JA:JA+N-1) is the matrix used to produce the factors stored in A(1:N,JA:JA+N-1)  and  AF  by
       PCGBTRF.
       A(1:N, JA:JA+N-1) is an N-by-N complex
       banded distributed
       matrix with bandwidth BWL, BWU.

       Routine PCGBTRF MUST be called first.
