MATLAB File Help: prtNewKernel
  prtNewKernel creates a new prtClass* M-file
    prtNewKernel creates a new prtKernel* M-file including definitions for
    all required methods and properties for prtKernel objects.  By
    convention, prtKernel M-files should start with the string prtKernel, and
    file names must be valid MATLAB function names (no special characters,
    spaces, etc.)
    prtNewKernel(FILENAME) enables the user to specify the name of the new
    prtKernel object from the command line.
