PSO解决40个机组优化问题，适合初学的同学(PSO solve 40 units optimization problems)

分东西和南北两个路口模拟交通三色信号灯的亮灭控制(East and West and North-South two intersection points simulated three-color traffic signal control of bright eliminate)

This project consists of two back to back pwm converters used for simulation of traction load in normal operating mode. The first side is connected to a single phase network and uses hysteresis current control. The second side is connected to a three phase network and uses space vector modulation for controlling its inverter.

基于matlab/simulink搭建的三电平逆变器仿真模型，控制算法为电压空间矢量控制（SVPWM），算法部分使用m语言编写，带有简单注释，配合算法说明，应该比较好懂。模型带中点电压平衡处理，但是效果一般，大家可以在此模型基础上修改。欢迎交流讨论。(Three-level inverter simulation model matlab/simulink structures based control algorithms for the voltage space vector control (SVPWM), part of the algorithm using the m language, with a simple comment, with the algorithm description, it should be relatively easy to understand. Models with the midpoint voltage balanced, but the general effect, you can modify the model basis. Welcome exchanges and discussions.)

matlab双线性插值算法实现图像放大源代码(matlab bilinear interpolation algorithm to enlarge the image)

多种降维方法的一个程序包，包括PCA,ISOMAP, LLED等,GUI，界面直观简单(A variety of dimensionality reduction method package, including PCA, ISOMAP, LLED etc., GUI, simple and intuitive interface)

matlab实现矩形脉冲和根升余弦脉冲的QPSK调制功率谱密度及不同信噪比信道下的星座图，直接运行main函数即可(Plot the power density spectrum of the transmitted signal (e.g., with the matlab function psd) with different pulse shapes. How is it affected if a root raised cosine pulse is chosen instead of a rectangular pulse shape? Study the signal constellation in the receiver for various values of Eb/N0 for the AWGN channel. )

能在一张有字母的图片中找出某一个字母在该图中所出现的所有位置(There are letters in a picture in a letter to find a figure that appears in the location of all)

分别使用LS和TLS算法，计算出混合信号的频率。该频率估计算法的数学模型是基于ARMA模型。其中还包括详细的设计报告，有一定的参考价值。(LS and TLS algorithms were used to calculate the mixed-signal frequency. The mathematical model of the frequency estimation algorithm is based on ARMA models. It also includes detailed design report, a certain reference value.)
