说明：  一本matlab的虚拟现实的讲义，书写的还不错！(A virtual reality matlab lecture notes, writing bad!)

车牌分割与识别，是现在交通电子眼必备的系统，本程序就是用matlab程序实现车牌的分割与识别，(License plate segmentation and recognition, is now an essential transport system of electronic eyes, the procedure is to use matlab program to achieve license plate segmentation and recognition,)

：在介绍过程监控主要内容及方法的基础上，归纳分析了统计过程监控的发展，详细阐述了传统 的PCA、PCR、PLS、FDA、HMM 和几种改进的PCA方法．指出，将人的经验和专家知识融人到PCA统计过程 监控，提高PCA的故障检测、隔离能力，完善故障诊断与评价能力，将是一个有价值的研究方向(: In the introduction the main content and methods of process monitoring based on the inductive analysis of the statistical process monitoring of development, elaborated on the traditional PCA, PCR, PLS, FDA, HMM, and several improved PCA method. Pointed out that the human experience and financial expertise to the PCA statistical process monitoring of people and improve the PCA fault detection, isolation, and improve fault diagnosis and evaluation capacity, will be a valuable research)

This program applies Upsampling on a speech file.

调用函数，并对函数进行求解，把数据存储，并画出其中几条图(Call the function, and the function is solved, the data is stored, and draw the diagram in which several)

不是直接调用函数，直接计算出IIR参数的IIR滤波器设计。一共12个滤波器，从IIR一阶和切比雪夫滤波器都有。(not directly call functions directly calculated parameters of IIR IIR filter design. A total of 12 filters, IIR from a band and the Chebyshev filter has.)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。 (This is based on space-time block coding MIMO_OFDM communication system simulation design. This system includes the QPSK modem, IFFT modulation, space-time coding and decoding, symbol-based channel estimation training and other communication module.)

laboratory work in matlab

Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.
