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

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

       PDPTSV solves a system of linear equations

       where A(1:N, JA:JA+N-1) is an N-by-N real
       tridiagonal symmetric positive definite distributed
       matrix.

       Cholesky factorization is used to factor a reordering of
       the matrix into L L'.

       See PDPTTRF and PDPTTRS for details.
