pdgbsv3
Solve a system of linear equations a(1:n, ja:ja+n-1) * x = b(ib:ib+n-1, 1:nrhs)
Purpose
PDGBSV solves a system of linear equations
where A(1:N, JA:JA+N-1) is an N-by-N real
banded distributed
matrix with bandwidth BWL, BWU.
Gaussian elimination with pivoting
is used to factor a reordering
of the matrix into P L U.
