% pushbutton_CallWFTKernel M-file for pushbutton_CallWFTKernel.fig
% pushbutton_CallWFTKernel, by itself, creates a new pushbutton_CallWFTKernel or raises the existing
% singleton*.
%
% H = pushbutton_CallWFTKernel returns the handle to a new pushbutton_CallWFTKernel or the handle to
% the existing singleton*.
%
% pushbutton_CallWFTKernel('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in pushbutton_CallWFTKernel.M with the given input arguments.
%
% pushbutton_CallWFTKernel('Property','Value',...) creates a new pushbutton_CallWFTKernel or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before WFT_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to WFT_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
