利用ＭＡＴＬＡＢ软件对不同偏振光在真空、各向同性介质、线型各向异性介质以及圆型各向异性介质中的传播过程进行了三维动态模拟(Different polarized light propagation in vacuum, isotropic medium, linear anisotropic media, as well as round anisotropic media, three-dimensional dynamic simulation using MATLAB software)

k-d树的matlab程序，包含了KDTREE, KDTREEIDX and KDRANGEQUERY functions。提供了两个Demo scripts(kdtree_demo.m & kdrange_demo.m),很实用( This distribution contains the KDTREE, KDTREEIDX and KDRANGEQUERY functions. Included are the source code files in kdtree/src, as well as precompiled mex files for the following systems: - Mac OS X (Matlab 6.5) - Redhat Linux (Matlab 6.5) - Windows (Matlab 6.1) Two demo scripts are provided (kdtree_demo.m & kdrange_demo.m). The new features added June 2004: + You can now use N dimensional data points, where N>3. + Use KDTREEIND to return the index value to the closest point, instead of the closest point values. + KDRANGEQUERY can now return these index values as well.

根据三次B样条公式，算出样条曲线，并取样，把三维坐标写进txt，再用matlab绘制三维三次B样条曲线(According to the cubic B-spline formula, calculate the spline curve, and sample, the three-dimensional coordinates into the txt, and then draw three-dimensional cubic B-spline curve)

这是一个基于一维语音信号的自动消噪代码，采用的是启发式阈值(This is a automatic denoising code based on wavelet transform for one-dimensional signal,we use the heuristic threshold )

CORDIC sin cos algorithm 2

主要介绍matlab的相关内容 可以提供初学者自学用 (Introduces relevant content matlab beginners can provide self-learning)

Alamouti 码字的matlab编程实现，2发1收的全分集增益的一种编码方法。(Alamouti code use matlab language，2 transmit antenna and 1 receive antenna。)

Hilbert 用于心电信号的检测，提取R波(Hilbert detect the R wave in the ECG )

PMSG网侧的结构包括逆变器、PWM发生器、电压矢量控制。采用电压外环和电流内环的双闭环控制。设计电流控制器时，希望稳态电流无静差，而且动态要求上，永磁直驱风力发电系统中不允许在电流调节过程中有太大的电流超调.(PMSG network side structure includes an inverter, PWM generators, voltage vector control. Using a voltage outer and inner current double closed loop control. Design current controller, hope no static error steady-state current, and the dynamic requirements, permanent magnet direct drive wind power system does not allow much of the current overshoot in the current regulation process.)
