基于matlab的信号采集处理系统（GUI界面）

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