Here is a start:
1 - In Core/arch/SSE/MathFunctions.h: The sin, cos, exp, and log
functions of this file come from Julien Pommier's sse math library:
http://gruntthepeon.free.fr/ssemath/
Licence: zlib which is BSD-like, so no big deal.
2 - In Ordering/AMD.h: the approximate minimum degree ordering
algorithm comes from CSparse (Timothy Davis).
Licence: LGPL2.1+
3 - In SparseCholesky/SimplicialCholesky.h: the factorization code
initially comes from the LDL Library of Timothy Davis.
Licence: LGPL2.1+
4 - In IterativeLinearSolvers/IncompleteLUT.h: the algorithm is
inspired from SPARSKIT package, Copyright (C) 2005, the Regents of the
University of Minnesota (Yousef Saad)
The original code was fortran 90, so its a complete rewrite using
the fortran code as a reference of the high level algorithm.
