kd-tree 是广泛用来处理多维寻找最近点的数据结构。该文件中是由matlab调用c++代码实现的，其中实现包括kd-tree的建立最近点的查找等。(kd-tree is kind of data structure which is widely used to find the nearest point in multi-demensions.The zip file contain matlab and cpp files.The functions implemented include kd-tree building and nearest points searching and so on.)

适用于数学建模，基于matlab的灰色预测代码(For mathematical modeling, based on gray prediction matlab code)

Matlab codes for face matching using fisher faces approach.

计算目标跟踪脱靶距离的一种OSPA距离算法(Calculation of target tracking a miss distance: OSPA distance algorithm)

有关多相滤波的matlab的程序实现，是一个很高的学习例程，有助于对matlab和多相滤波的学习(On the polyphase filter matlab realize the procedure is a very high learning routines, help to matlab and polyphase filter learning)

本文为Stephen J.Chapman《MATLAB 编程（第二版）》英文影印版的中文译本，这本 书对初学者很好的入门教材(This article Stephen J.Chapman MATLAB Programming (second edition), the English version of the Chinese translation of photocopying, this A good book for beginners introductory textbook)

非常有用的matlab 程序例子，三维球面程序！！(It is very usefull to draw a ball.)

过这个程序，可以更加深入的了解FIR滤波是如何实现的。用AVR单片机 ATMEGA16L实现32阶FIR低通滤波器设计，低通截止频率为200HZ。原始信号经过AD采集后进行FIR运算，处理好的数据通过串口输出。(About this program, a more in-depth understanding of the FIR filter is how to achieve. The 32-order FIR low-pass filter design, low-pass cut-off frequency AVR microcontroller ATMEGA16L 200HZ. The original signal after AD collection, the FIR computation, the output of the processed data through the serial port.)

说明：  QPSK调制的Matlab程序。包含了QPSK调制及误码率分析。可以调制一随机产生的序列来分析误码率，也可以调制一幅图像来分析误码率。(QPSK modulation of the Matlab program. Contains a QPSK modulation and BER analysis. Can be modulated to a randomly generated sequence analysis of BER, an image can also be prepared to analyze the error rate.)
