介绍SOWAS.0.93.Matlab(小波分析与合成软件)，另含R语言版

hillside

      SOWAS是小波分析与合成的简称（Software for Wavelet Analysis and Synthesis），软件原始下载链接已转向东英吉利大学，但似乎难以找到源程序位置，本帖提供的源程序下载自其他地方。

      该软件中包括多个气候实例数据。

      按网页介绍，需要与以下网址软件http://atoc.colorado.edu/research/wavelets/software.html一并使用：

   

Package: sowas

Version: 0.92

Date: 2007-05-17

Title: Software for Wavelet Analysis and Synthesis

Author: Douglas Maraun <d.maraun@uea.ac.uk>

Translation to Matlab: Jonas Laehnemann

Maintainer: Douglas Maraun <d.maraun@uea.ac.uk>

Description: The package calculates wavelet sample spectra and

    wavelet sample coherency aswell as corresponding pointwise

    and areawise significancetests.

    It also generatesrealizations of any wavelet sample

    spectrum.

License: GPL version 2 or newer

URL: http://tocsy.agnld.uni-potsdam.de/wavelets/

This package is also available as R routine.

The Package contains the following Matlab scripts

(further documentation in the headers of the files):

* wsp.m - This funtion estimates (and possibly plots) the waveletspectrum

  of a time series object withthe Morlet wavelet.

* wco.m - This funtion estimates the wavelet coherency of two timeseries

  objects with the Morletwavelet.

* wcs.m - This funtion estimates the wavelet cross spectrum of two time

  series objects with the Morletwavelet.

* plotwt.m - This function plots wavelet transform objects from thefunctions

  wsp,wcs,wco. Modulus and (ifpossible) phase are plotted.

The following functions perform the significance tests. They are calledby

wsp.m and wco.m and therefore should only be used as standalone if youknow

what you're doing.

* arealtest.m - Perform Areawise Significance Test.

* criticalvaluesWCO.m - This function estimates critical values for the

  wavelet coherency between twoprocesses using the Morlet wavelet based

  on a formula derived from Monte Carlo simulations.

* criticalvaluesWSP.m - This function estimates critical values for the

  Wavelet spectra by means of Monte Carlo simulations. Null Hypothesis is

  an AR1 (red noise) processfitted to the given time series.

Other small functions the above depend on:

  addvalues.m, adjustnoctave.m,adjusts0.m, adjusttimeseries.m,

  checkarealsiglevel.m,scalematrix.m, smoothmatrix.m, smoothtime.m

                                                             小波变换中的非平稳高斯过程
    我们提出了一个等价类中定义的小波域非平稳高斯随机过程。这些过程的特点由小波乘法器的装置和具有良好定义的时间依赖性的光谱特性。他们让一个产生任何小波频谱的实现。基于这一框架，我们研究了连续小波谱，即估计，我们计算出的任意连续小波估计谱的方差和偏差。最后，我们发展的areawise的显着性检验为连续小波变换光谱克服困难的多个测试，它使用连续小波变换的基本性质。决定是否逐点显着的结果是一个真正的功能的过程中或从典型的随机波动没有什么区别。此测试相比，传统的一个方面的敏感性和特异性。一个软件包为连续小波变换的频谱分析和综合的方法。
