Use a template Index for COLAMD ordering
Bug567 : Fix iterative solvers to immediately return when the initial guess is the true solution and for trivial solution
Add SSE4 min/max for integers
Add complex support to dgmres and the unit test
Allow multiplication like binary operators to be applied on type couples supported by scalar_product_traits
adapt AutoDiff to scalar_product_traits
Fix warning: implicit conversion loses integer precision in SparseMatrix. No need to use std::ptrdiff_t instead of Index since this later is requested to be signed.
