The Iterative Template Library Alpha Release The Iterative Template Library (ITL) has two parts, iterative solvers and preconditioners. ITL provides a collection of sophisticated Krylov subspace iterative solvers that use basic linear algebra packages such as the Matrix Template Library or Blitz++ for its basic linear algebra operations. The ITL has extended many of the ideas of the Iterative Methods Library (IML++), to make the library more flexible. The "interface" is to specify basic linear algebra operations. See next bullet for details. On the other hand, ITL also provides a set of preconditioners which are designed for Matrix Template Library. The latest documentation for ITL can be found on our website: WWW: http://www.osl.iu.edu/research/itl
