The Iterative Template Library (ITL) is a generic component library that provides iterative methods for solving linear systems. ITL also provides numerious preconditioners which is for MTL. ITL uses the abstract interface of matrix-vector, vector-vector, and vector-scalor operations MTL is default to serve those operations. ITL is able to use other packages such as Blitz++ and BLAS with the same abstract interface provided.
