solution to nonlinear equations use stepsize methode

The Akaike information criterion (AIC) is a measure of the relative quality of a statistical model for a given set of data. That is, given a collection of models for the data, AIC estimates the quality of each model, relative to each of the other models. Hence, AIC provides a means for model selection.

This program is an implementation of the k-means algorithm with matlab.

模拟FM信号的解调子程序，包括下变频、A/D采样、正交解调，最后输出基带信号。(Subroutine analog FM demodulation signal, comprising down-conversion, A/D sampling, orthogonal demodulation, and finally outputs a baseband signal.)

一些MATLAB应用程序，MATLAB计算机模拟(Some MATLAB application, MATLAB simulation)

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.)

一个自己编写的matlab程序，仅供大家学习参考(PLL I have written an example, we learn for reference purposes only)
