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