CHARACTER TRANS, UPLO  
INTEGER BWL, BWU, IB, INFO, JA, LAF, LWORK, N, NRHS  
INTEGER DESCA( * ), DESCB( * )  
DOUBLE PRECISION A( * ), AF( * ), B( * ), WORK( * )  
PDDBTRSV solves a banded triangular system of linear equations A(1:N, JA:JA+N1) * X = B(IB:IB+N1, 1:NRHS) or
A(1:N, JA:JA+N1)^T * X = B(IB:IB+N1, 1:NRHS)where A(1:N, JA:JA+N1) is a banded
triangular matrix factor produced by the
Gaussian elimination code PD@(dom_pre)BTRF
and is stored in A(1:N,JA:JA+N1) and AF.
The matrix stored in A(1:N, JA:JA+N1) is either
upper or lower triangular according to UPLO,
and the choice of solving A(1:N, JA:JA+N1) or A(1:N, JA:JA+N1)^T is dictated by the user by the parameter TRANS.Routine PDDBTRF MUST be called first.
