MATLAB GUI选择参数绘制曲线

function varargout = matlab_GUI8(varargin) % MATLAB_GUI8 MATLAB code for matlab_GUI8.fig % MATLAB_GUI8, by itself, creates a new MATLAB_GUI8 or raises the existing % singleton*. % % H = MATLAB_GUI8 returns the handle to a new MATLAB_GUI8 or the handle to % the existing singleton*. % % MATLAB_GUI8('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in MATLAB_GUI8.M with the given input arguments. % % MATLAB_GUI8('Property','Value',...) creates a new MATLAB_GUI8 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before matlab_GUI8_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to matlab_GUI8_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
