Butterfly

This page contains an applet that should appear as a separate window.

For this demo to work you will need: * A Java compiler, typically the javac program found in the JDK, see http://java.sun.com/javase/downloads/index.jsp * make and a C compiler. Under Windows, you may need to install Cygwin, see http://ptolemy.eecs.berkeley.edu/ptolemyII/ptIIlatest/cygwin.htm Under Windows, you may need to add C:\cygwin\bin to your path. * This model uses the plotter, so it requires that jvm.dll be in your path. This file can be found in the jre/bin/client directory of the JDK, so you may need to add a director like c:\Progra~1\Java\jdk1.5.0_14\jre\bin\client to your path. Ptolemy attempts to temporarily add the proper directory to your path, but it might not always succeed. If the generated executable starts up and then exits, you may need to the directory that contains libjvm.dll directly to your path and then run the generated executable. * Under Windows, you may need to add c:\Cygwin\bin to your path to avoid the "impure_ptr" message.
