A MATLAB-like matrix-oriented programming language/toolbox. RLaB focusses on creating a good experimental environment (or laboratory) in whICh to do matrix mathematICs. Currently RLaB has numerIC scalars and matrICes (real and complex), and string scalars, and matrICes. RLaB also contains a list variable type, whICh is a heterogeneous associative array. Version 0.95 includes an interpreter, libraries and documentation. E-mail: Ian Searle . . Requires GNUPLOT, lib[IF]77.a (from f2c). Ported to many platforms including Unix, OS/2, Amiga. (1993-10-27).
