RLaB is an interactive, interpreted scientific programming environment which provides fast prototyping and program development. Its syntax is a combination of c (curly brackets for blocks of statement, some statements) and fortran/matlab (c) (indexing of arrays starts from 1, naming of the functions).
Project rlabplus provides second update to RLaB2 and third release RLaB3 of the environment for 32- and 64-bit linux systems.
