⛄ 内容介绍
为了加强学生对"信号与系统"课程理论知识的掌握及提高其解决实际问题的能力,同时给课堂教学添加活力,建立基于 MATLAB的实验仿真系统.此实验仿真系统用GUI实现图形用户界面,以便于学生认识和操作.这使得利用计算机辅助完成该课程相关分析的可视化建模及仿真调试成为可能.
⛄ 部分代码
function varargout = GUI_Start(varargin)
% GUI_START MATLAB code for GUI_Start.fig
% GUI_START, by itself, creates a new GUI_START or raises the existing
% singleton*.
%
% H = GUI_START returns the handle to a new GUI_START or the handle to
% the existing singleton*.
%
% GUI_START('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in GUI_START.M with the given input arguments.
%
% GUI_START('Property','Value',...) creates a new GUI_START or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before GUI_Start_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to GUI_Start_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
