++ * \defgroup IterativeLinearSolvers_Module IterativeLinearSolvers module
++ *
++ * This module currently provides iterative methods to solve problems of the form \c A \c x = \c b, where \c A is a
++ squared matrix, usually very large and sparse.
++ * Those solvers are accessible via the following classes:
++ * - ConjugateGradient for selfadjoint (hermitian) matrices,
++ * - LeastSquaresConjugateGradient for rectangular least-square problems,
++ * - BiCGSTAB for general square matrices.
++ *
++ * These iterative solvers are associated with some preconditioners:
++ * - IdentityPreconditioner - not really useful
++ * - DiagonalPreconditioner - also called Jacobi preconditioner, work very well on diagonal dominant matrices.
++ * - IncompleteLUT - incomplete LU factorization with dual thresholding
++ *
++ * Such problems can also be solved using the direct sparse decomposition modules: SparseCholesky, CholmodSupport,
++ UmfPackSupport, SuperLUSupport, AccelerateSupport.
