      SUBROUTINE SPTSL(N,D,E,B)

DESCRIPTION    [Toc]    [Back]

     On	Entry

     N INTEGER
	is the order of	the tridiagonal	matrix.

     D REAL(N)
	is the diagonal	of the tridiagonal matrix.
	On output, D is	destroyed.

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

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

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