Computes the solution of:

     <center> <b> A x = b </b> </center>

     For a cyclic tridiagonal matrix A. The matrix cts is filled with
     the output of the function sll_s_setup_cyclic_tridiag.  Note that the
     call:

     sll_o_solve_cyclic_tridiag( cts, ipiv, b, n, b )

     is valid if you want run in-place and overwrite the right hand side
     with the solution.

Parameters

	cts	a real array of size 7n where factorization information will be returned
[in]	ipiv	an ineteger array of length n on wich pivoting information will be returned
	b	the second member of the equation
	n	the problem size
	x	the solution vector

solve_cyclic_tridiag_complex()

subroutine solve_cyclic_tridiag_complex ( target  cts, intent(in)  ipiv, dimension(n), target  b, intent(in)  n, dimension(n), target  x  )

private

Parameters

	cts	a real array of size 7n where factorization information will be returned
[in]	ipiv	an ineteger array of length n on wich pivoting information will be returned
	b	the second member of the equation
	n	the problem size
	x	the solution vector
