To activate an XFun, move the file from the "XFuns" folder to the "Active Xfuns" folder and restart MathPad.

Most XFuns contain short examples that will be available under the Help menu once the XFun is installed.

The files in this folder give some longer examples using the Xfuns:

  fft
  showPICT
  readgray
  viewsurf
