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

- COMPLEX*16 B( * ), D( * ), DL( * ), DU( * ), WORK( * )
PURPOSE
PZDTSV solves a system of linear equationswhere A(1:N, JA:JA+N-1) is an N-by-N complex
tridiagonal diagonally dominant-like distributed
matrix.
Gaussian elimination without pivoting
is used to factor a reordering
of the matrix into L U.
