PDDTSV(l) ) PDDTSV(l)NAME
PDDTSV - solve a system of linear equations A(1:N, JA:JA+N-1) * X =
B(IB:IB+N-1, 1:NRHS)
SYNOPSIS
SUBROUTINE PDDTSV( N, NRHS, DL, D, DU, JA, DESCA, B, IB, DESCB, WORK,
LWORK, INFO )
INTEGER IB, INFO, JA, LWORK, N, NRHS
INTEGER DESCA( * ), DESCB( * )
DOUBLE PRECISION B( * ), D( * ), DL( * ), DU( * ), WORK( *
)
PURPOSE
PDDTSV 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 an N-by-N real
tridiagonal diagonally dominant-like distributed
matrix.
Gaussian elimination without pivoting
is used to factor a reordering
of the matrix into L U.
See PDDTTRF and PDDTTRS for details.
