matlab实现的DS-CDMA模块，功能齐全，适合使用(matlab cdma)

matlab的维纳滤波器源码，内容较少，但滤波器的功能都有！(the source code of Wiener filter)

这是一个关于垂直腔半导体光放大器（VCSOA，微腔光放大器的一种）中的双稳态曲线计算程序，用Matlab语言写成，可执行。程序是根据VCSOA中的速率方程（Rate Equation）编写的。从曲线上可以看出随着输入功率Pin的变化VCSOA的输出功率Pout的双稳态曲线，是进一步研究该问题的基本素材之一。(This is a computation program for calculating the bistability activity of the vertical cavity semiconductor optical amplifier, which is based on the rate equation in VCSOA. This code is a basis for further investigating other activities in VCSOA related to bistability. )

说明：  采用粒子群算法结合MATPOWER对GARVER-6配电网系统进行交流潮流计算并进行网架规划(AC power flow calculation and grid planning for GARVER-6 distribution system using particle swarm optimization and MATPOWER)

说明：  本程序来自TI公司网站原程序,其功能是通过传统的矢量控制算法来实现对永磁同步电机的控制,矢量控制采用双闭环结构，内环为电流环，外环为速度环，其速度的获得是靠滑模自适应算法求得。是一个不可多得无速度传感器矢量控制例程。控制程序可以采用.asm也可以采用.C。程序的具体算法和介绍在软件压缩包有详细介绍！ (this program from the company's Web site TI program, its function is through the traditional vector control algorithm to achieve the permanent magnet synchronous motor control, vector control double-loop structure for the inner loop current loop, velocity loop to the outer ring, the speed was on sliding mode is obtained adaptive algorithm. It is a rare speed sensorless vector control routines. Control procedures can be taken. Asm also be used. C. The specific procedures and the introduction of the algorithm compression software packages are described in detail!)

四种天线阵列加权分布。泰勒分布、二项式分布、傅里叶分布、切比雪夫分布。(Four kinds of antenna array weighted distribution.Taylor distribution, binomial, Fourier, chebyshev distribution.)

数字图像处理，实现图像分割，旋转，灰度变换(matlab digital image processing the image gray-scale processing, segmentation processing, rotation processing)

This tutorial is designed to give the reader an understanding of Principal Components Analysis (PCA). PCA is a useful statistical technique that has found application in fields such as face recognition and image compression, and is a common technique for finding patterns in data of high dimension. Before getting to a description of PCA, this tutorial first introduces mathematical concepts that will be used in PCA. It covers standard deviation, covariance, eigenvectors and eigenvalues. This background knowledge is meant to make the PCA section very straightforward, but can be skipped if the concepts are already familiar.
