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.

FFTW is an optional dependency; it will be used if it is found.
