1/25/92: Rlab is _not_ a clone of languages such as those used by tools like MATLAB or matrix_X/Xmath. However, as Rlab focuses on creating a good experimental environment (or laboratory) in which to do matrix math, it can be called "MATLAB-like" since the programming language possesses similar operators and concepts. Extensive use has been made of the LAPACK, FFTPACK and RANLIB sources available from netlib. The most significant difference between the other proprietary tools and RLaB is the GNU Copyleft. See the file INSTALL for installation instructions. See the file INSTALL.2 for a guided installation. See the file WHATS.NEW for release news. See the file PROBLEMS for solutions to some commonly encountered installation/operation problems. See the examples directory for simple examples on how to use the program, and the plotting capabilities. See the RlaB Primer for a guided tour of the program, and more examples.
