TOEPLITZ, a FORTRAN90 code which solves a variety of Toeplitz and circulant linear systems.
The package can also handle circulant Toeplitz systems, and some other more complicated but related forms.
The TOEPLITZ package was written in the early 1980's by a joint working group of American and Soviet mathematicians.
The original, true, correct version of TOEPLITZ is available in the TOEPLITZ subdirectory of the NETLIB web site.

TOEPLITZ is available in a FORTRAN90 version.
