PDDBTRS solves a system of linear equations
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 PDDBTRF.
A(1:N, JA:JA+N-1) is an N-by-N real
banded diagonally dominant-like distributed
matrix with bandwidth BWL, BWU.
Routine PDDBTRF MUST be called first.
