fs.m

matlab中用于进行fourier变换的GUI程序

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