pronytool.m

Prony算法工具箱。Prony方法是用一组指数项的线性组合来拟和等间距采样数据的方法,可以从中分析出信号的幅值、相位、阻尼因子、频率等信息。considerations including data

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