用matlab 计算李雅谱诺夫指数功率谱哦，呵呵呵，可以下哦(lyp dajia key xiao heheh good)

根据系统的阶跃响应，计算时域性能指标（比如超调量、峰值、调节时间等）。(According to the step response of the system, calculate the time-domain performance indicators (such as overshoot, peak, adjust the time).)

基于星座图的QPSK调制解调程序，功能函数，可以直接调用进行QPSK调制解调(Based on a constellation of QPSK modulation and demodulation process, the performance function can be called directly conduct QPSK modulation and demodulation)

文章是介绍基于MATLAB开发的混合燃料电池汽车仿真软件ADVISOR2002的二次开发的方法(The article is to introduce the MATLAB-based development of hybrid fuel cell vehicle simulation software ADVISOR2002 the secondary development of methods)

本论文主要利用MATLAB实现一个简单无线通信系统的仿真，并通过误码率分析系统性能。在文本文件中输入任意字符串(空格或英文字母)作为该通信系 统的信源，经过信源编码、信道编码及信号调制进入信道，信道采用的是瑞利衰落信道，而后对接收到的信号进行解调，完成信道解码、信源解码后，将结果输出到解码文件即信宿中。 (In this thesis, a simple wireless communication system simulation using MATLAB and analyze system performance through the bit error rate. In a text file input any string (spaces or English letters) as the communication system of the letter source, source coding, channel coding and signal modulation into the channel, the channel using the Rayleigh fading channel, the signal is received and then docking demodulates the completion of the channel decoding, source decoding, the result is output to decode the file, i.e. the sink.)

二维波导中计算反射系数，两边为PML，上下为PEC，波源为平面波(two-dimensional waveguide reflection coefficient calculated on both sides of the PML and bottom of the PEC, for the plane wave Boyuan)

主元分析方法，主要用于提取主元，数据降维(Principal components analysis)

. The 8-puzzle problem is a puzzle invented and popularized by Noyes Palmer Chapman in the 1870s. It is played on a 3-by-3 grid with 8 square blocks labeled 1 through 8 and a blank square. Your goal is to rearrange the blocks so that they are in order. You are permitted to slide blocks horizontally or vertically into the blank square. The following shows a sequence of legal moves from an initial board position (left) to the goal position (right).
