It is an interactive expert system and programming environment for symbolic and numerical mathematical manipulation. Written in LISP, it allows differentiation, integration, solution of linear or polynomial equations, factoring of polynomials, expansion of functions in Laurent or Taylor series, computation of Poisson series, matrix and tensor manipulations, and two- and three-dimensional graphics. Procedures may be written using an ALGOL-like syntax, and both LISP-like functions and pattern matching facilities are provided. Files containing maxima objects may be read from and written to disk files. Pre-written maxima commands may be read from a file and executed, allowing batch-mode use. There are RPMs for it in the Fedora Extras repository. --- Vladimir -- Vladimir G. Ivanovic Palo Alto, CA 94306 +1 650 678 8014
