Matlab信号发生器-三角波、正弦波、方波

function varargout = fashengqi1(varargin) % FASHENGQI1 MATLAB code for fashengqi1.fig % FASHENGQI1, by itself, creates a new FASHENGQI1 or raises the existing % singleton*. % % H = FASHENGQI1 returns the handle to a new FASHENGQI1 or the handle to % the existing singleton*. % % FASHENGQI1('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in FASHENGQI1.M with the given input arguments. % % FASHENGQI1('Property','Value',...) creates a new FASHENGQI1 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before fashengqi1_OpeningFcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to fashengqi1_OpeningFcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
