Decompose image into subbands (undecimated wavelet), denoise, and recompose again. fh = decomp_reconst_wavelet(im,Nsc,daub_order,block,noise,parent,covariance,optim,sig) im : image Nsc: Number of scales daub_order: Order of the daubechie fucntion used (must be even). block: size of neighborhood within each undecimated subband. noise: image having the same autocorrelation as the noise (e.g., a delta, for white noise) parent: are we including the coefficient at the central location at the next coarser scale? covariance: are we considering covariance or just variance? optim: for choosing between BLS-GSM (optim = 1) and MAP-GSM (optim = 0) sig: standard deviation (scalar for uniform noise or matrix for spatially varying noise) Javier Portilla, Univ. de Granada, 3/03 Revised: 11/04

用matlab去计算无缺陷的有限周期光子晶体的带隙问题(Using matlab to calculate the defect-free for a limited period photonic crystal band gap problem)

说明：  此程序实现求任一信号的幅频响应，需知的参数有待求信号及其采样率。(The programme realize to get amplitude frequency response.)

利用Kaveh法估计ARMA过程功率谱，只需计算AR系数，简化过程。(Kaveh estimation using ARMA process of the power spectrum, simply calculating AR coefficients, to simplify the process.)

这是根据提交的亚历山大Gramfort的“MATLAB的网状到PDF与三维交互对象“。他的计划将允许网数字转换成3D PDF格式。然而，他的代码只允许一个层进行转换，并不会启用的透明度。 本意见书不创建最终的PDF。它产生的U3D文件，然后可以使用到PDF的Adobe Acrobat Pro文件插入。本文件还允许多层网格，以创建，并为每个层的透明度指定。 此代码包含一个函数（installGoogleArchive.m），它会自动下载并安装所需的中间数据格式转换（IDTF）进入最后的通用3D（U3D）文件的二进制文件。此代码还只包括转换器的Windows版本。(This submission is based on Alexandre Gramfort s "matlab-mesh-to-pdf-with-3d-interactive-object". His program allows meshes to be converted into 3D PDF figures. However, his code only allows a single layer to be converted, and does not enable transparency. The present submission does not create the final PDF. It generates the U3D file which can then be inserted into a PDF file using Adobe Acrobat Pro. This submission also allows multilayer meshes to be created, and for the transparency of each layer to be specified. This code includes a function (installGoogleArchive.m) which will automatically download and install binaries required to convert the intermediate data format (IDTF) file into the final Universal 3D (U3D) file. This code also only includes the windows version of the converter.)

while modeling a discrete event problem you may need to know how to create a random num.
