Math Applets

The mathapps package contains a number of simple data source Physlets.  Since they are designed to deliver data to other Physlets, they have a very minimal user interface.

FFT

The FFT routine used in the mathapps.FFT applet  uses the jnt.fft package that was developed by Bruce Miller at NIST. Several routines in this subpackage are Java ports of routines derived from Brian Gough's FFT routines in the Gnu Scientific Library (GSL). GSL is released under the Gnu General Public License; As such, this package must also be released under GPL.

The Physlet code for the mathapps.FFT applet may be downloaded here.  This code is also being released under he Gnu General Public License.
