- Does anyone know of any fortran routines available to solve
- tridiagonal systems using cyclic reduction? I would like something
- along the lines of the routines in _Numerical Recipes_ (W. H. Press
- et al., 1986, Cambridge University Press); unfortunately, that
- book does not have a cyclic reduction routine. I realize that
- the LIBSCI library on the Cray's has such routines, but I need
- to have a portable code.
