【语音处理】基于matlab GUI语音信号IPC分析【含Matlab源码 910期】

本文主要是介绍【语音处理】基于matlab GUI语音信号IPC分析【含Matlab源码 910期】，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、简介

基于matlab GUI语音信号IPC分析

二、源代码

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