this is a a assembly code for multipattern running lights

介绍了MATLAB工程应用中常用命令，全面且易懂。(Introduce the common orders of Matlab, which is easy to understand and colorful)

simulates a digital communication system with QPSK signal waveforms in Fig.7.7

对于初学者具有参考意义，光纤无线通信系统中传输性能的研究，最小均方误差等算法的MSE的计算。( For beginners with a reference value, Fiber Transmission wireless communication system performance, Minimum mean square error MSE calculation algorithm.)

精度颇高的转子临界转速及不平和响应算法，主要采用了传递矩阵法(High precision of the rotor critical speed and the uneven and response algorithms, mainly in the transfer matrix method)

MATLAB 开发滤波输出系统，可以高低波选择波段，并且为双屏显示(MATLAB development filtered output system, you can choose the level of wave band, and for dual display)

应用鸟群算法（PSO）优化全局神经网络权值，可以使用(Applications birds (PSO) algorithm to optimize the overall neural network weights, you can use)

非常有用的程序，可以调用来处理循环平稳信号，用以产生三维自相关图形。(Very useful program, you can call to handle the cyclostationary signals to generate three-dimensional self-related graphics.)

1. 设计一个 N = 10 的低通 fir 滤波器，对 fs = 8kHz 的信号 fc = 2.5kHz 2. 设计等同性能的 IIR 滤波器 3. 定点实现，不能使用浮点 4. 测试多正弦波合成文件 MultiToneTest.wav 分析输出结果 5. 测试语音文件 sc03.wav 得到输出结果(1. Design a lowpass fir filter N = 10, for fs = fc 8kHz signal design equivalent of = 2.5kHz 2. 3. IIR filter performance fixed-point implementation, you can not use floating-point multi-sine wave synthesis document 4. Testing 5. Test MultiToneTest.wav analysis output file sc03.wav get voice output)

Its valentine week..pass this to engineer girlfriend..nd she will more happy by looking into this cute valentine heart made in matlab..
