SYNOPSYS
      SUBROUTINE DPTSL(N,D,E,B)

DESCRIPTION
     On Entry

     N INTEGER
        is the order of the tridiagonal matrix.

     D DOUBLE PRECISION(N)
        is the diagonal of the tridiagonal matrix.
        On output D is destroyed.

     E DOUBLE PRECISION(N)
        is the offdiagonal of the tridiagonal matrix.
        E(1) through E(N-1) should contain the
        offdiagonal.

     B DOUBLE PRECISION(N)
        is the right hand side vector.  On Return

     B contains the solution. LINPACK.  This version dated 08/14/78 .  Jack
