Octave

[3D graph] [Lorenz Attractor] GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

Please see this [Mailing List Thread] if you are having trouble compiling Octave 2.9.6 with GCC 3.x. After applying the patch, you'll need to run autogen.sh and configure again. This means you'll need to have a recent version of autoconf installed. Or, you can upgrade to GCC 4.x or you can wait for 2.9.7. So many options!
