MATLAB (MATrix LABoratory) a numerical computing environment and fourth-generation computing language. MATLAB allows signal processing and communication, image and video processing, control systems, test and measurement, computational finance, and computational biology.
GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command-line interface (CLI) for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB.
