In Reply to: Solving a Toeplitz matrix equation posted by Graham French on February 05, 1998 at 10:10:48:

: I have an equation of the form

: h(i,j)=M(i,j,k,l)g(k,l)

: where M is a symmetric semipositive definite block

: Toeplitz matrix.

: I need to either invert or solve for g iteratively in the

: most efficient way possible. Can anyone suggest

: a routine that they know of themselves or know of in the

: NetLib repository (preferably in fortran).

: I've heard of conjugate gradient and Levison algorithms, but

: I can't find them

: Many thanks

Graham French

The best way to find something like this at Netlib

is to use Netlib search engine. When I entered in

"Solving a Toeplitz matrix equation " and

"Conjugate gradient and Levison algorithms" , I got quite

a few hits'`, but I am unsure if any of the packages

are suitable for your needs....

Hope this helps !
