【数字信号】基于matlab GUI正弦信号时域+频域分析【含Matlab源码 887期】

一、简介

基于matlab GUI正弦信号时域、频域分析

二、源代码

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