zyx6.m

控制系统仿真中的频率特性的MATLAB源码

function varargout = zyx6(varargin)
% ZYX6 M-file for zyx6.fig
%      ZYX6, by itself, creates a new ZYX6 or raises the existing
%      singleton*.
%
%      H = ZYX6 returns the handle to a new ZYX6 or the handle to
%      the existing singleton*.
%
%      ZYX6('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in ZYX6.M with the given input arguments.
%
%      ZYX6('Property','Value',...) creates a new ZYX6 or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before zyx6_OpeningFunction gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to zyx6_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
