especially targeted at applications in the field of analysis and
verification of complex systems.  These abstractions include convex
polyhedra, defined as the intersection of a finite number of (open or
closed) halfspaces, each described by a linear inequality (strict or
non-strict) with rational coefficients; some special classes of polyhedra
shapes that offer interesting complexity/precision tradeoffs; and grids
which represent regularly spaced points that satisfy a set of linear
congruence relations.  The library also supports finite powersets and
products of (any kind of) polyhedra and grids, a mixed integer linear
programming problem solver using an exact-arithmetic version of the simplex
algorithm, a parametric integer programming solver, and primitives for
termination analysis via the automatic synthesis of linear ranking
functions.")

outputs mathematical symbols directly instead of depicting them with ASCII

wxMaxima also features 2D and 3D inline plots, simple animations, mixing of
text and mathematical calculations to create documents, exporting of input and

;; Since the latest version of Trilinos is not necessarily supported by

;; An insightful source of information for building Trilinos for deal.II lies

    (description "Vc provides portable, zero-overhead C++ types for explicitly
data-parallel programming.  It is a library designed to ease explicit
vectorization of C++ code.  Its types enable explicitly stating data-parallel
operations on multiple values.  The parallelism is therefore added via the type
system.  Vc has an intuitive API and provides portability between different
compilers and compiler versions as well as portability between different vector
instruction sets.  Thus, an application written with Vc can be compiled for:
@enumerate
@item AVX and AVX2
@item SSE2 up to SSE4.2 or SSE4a
@item Scalar
@item MIC
@item NEON (in development)
@item NVIDIA GPUs / CUDA (in development)

Solution algorithms such as the preconditioned nonlinear conjugate

provided for applications written in C++ and Python.  Parallel
