绘制不同情况下的升余弦滚降系统频谱，并画出其各自对应的时域波形(Draw different circumstances raised cosine roll-off system spectrum, and draw their own corresponding time-domain waveform)

半监督极限学习机，基于matlab实现的在线分类算法，人工智能(demo sselm ,Semi-supervised extreme learning machine, online classification algorithm based on matlab, artificial intelligence)

用matlab实现算术编码，包含对数据的压缩和解压(Using matlab realize arithmetic coding, including the data compression and decompression)

转速反馈控制直流调速系统的仿真，该模型是转速负反馈闭环调速系统的MATLAB仿真模型(Speed feedback control DC drive system of the simulation, the model is a negative feedback loop Speed Control System of the MATLAB simulation model)

CLP Interface to LP/QP solver MEXCLP

说明：  建立并绘制任意信号的模糊函数。已在巴克码，线性调频，脉冲信号中测试过。(This program estimates and plots the ambiguity function for any signals. I have tested it for the Barker code, chirp signal, pulse signal. for good results the length of the input vector (Ut)should be more than 7. Example- a rectangular pulse should be described as[1 1 1 1 1 1 1]. Please, give your suggestions. it is made with the help of "xcorr" function (Author: R. Losada) in MATLAB and Ilia Iliev from TU-Sofia )

以固定电压输出的逆变器的matlab仿真源文件，我初学逆变器仿真的时候做的，对初学者肯定有用(The fixed voltage three-phase output inverter matlab simulation source, beginner when I do , for some students new to the inverter simulation certainly useful)

给定栅格图像及其变形后的栅格图像，请你首先确定各栅格交叉点的位移，然后采用控制栅格的方法编写实现图像几何校正的程序(Given its raster image raster image after deformation, you first determine the displacement of each grid intersection, and then using the method of preparation of the control grid of image geometric correction procedures)
