抽样定理仿真实现matlab GUI完整代码（课程设计）

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