A program and language for the numerical study of deterministic and stochastic dynamical systems, which may evolve in continuous or discrete time. It loads the definition of a dynamical system in an equation oriented language, translates this into C++, compiles and links this, and solves the equations numerically with the speed of a compiled (rather than interpreted) program. It has a GUI that allows the program to be controlled and the parameters changed easily. Available at ftp.uu.net/pub/math/gnans/. As of 2002-04-25, binaries for Irix, Solaris, and GNU/Linux were available at that location. ftp.mathematik.uni-bremen.de, supposedly the source of this mirror, doesn't seem to exist and ftp.math.uni-bremen.de doesn't have it. - FSF Staff
