%WFTKERNEL M-file for WFTKernel.fig
%      WFTKERNEL, by itself, creates a new WFTKERNEL or raises the existing
%      singleton*.
%
%      H = WFTKERNEL returns the handle to a new WFTKERNEL or the handle to
%      the existing singleton*.
%
%      WFTKERNEL('Property','Value',...) creates a new WFTKERNEL using the
%      given property value pairs. Unrecognized properties are passed via
%      varargin to WFTKernel_OpeningFcn.  This calling syntax produces a
%      warning when there is an existing singleton*.
%
%      WFTKERNEL('CALLBACK') and WFTKERNEL('CALLBACK',hObject,...) call the
%      local function named CALLBACK in WFTKERNEL.M with the given input
%      arguments.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
