“Lush is an object-oriented programming language designed for researchers, experimenters, and engineers interested in large-scale numerical and graphic applications. Lush is designed to be used in situations where one would want to combine the flexibility of a high-level, weakly-typed interpreted language, with the efficiency of a strongly-typed, natively-compiled language, and with the easy integration of code written in C, C++, or other languages.
Lush is Free Software (under the GPL license) and runs on GNU/Linux, Solaris, Irix, and Windows under Cygwin.
Lush can be used advantageously for projects where one would otherwise use a combination of an interpreted language like Matlab, Python, Perl, S+, or even (gasp!) BASIC, and a compiled language like C. Lush brings the best of both worlds by wrapping three languages into one: (1) a weakly-typed, garbage-collected, dynamically scoped, interpreted language with a simple Lisp-like syntax, (2) a strongly-typed, lexically-scoped compiled language that uses the same Lisp-like syntax, and (3) the C language, which can be freely mixed with Lush code within a single program, even within a single function. It sounds complicated, but it is not. In fact, Lush is designed to be very simple to learn and easy to use.
If you do research and development in signal processing, image processing, machine learning, computer vision, bio-informatics, data mining, statistics, simulation, optimization, or artificial intelligence, and feel limited by Matlab and other existing tools, Lush is for you. If you want a simple environment to experiment with graphics, video, and sounds, Lush is for you…”
