航空电源270VDC供电系统simulink仿真，内包括原理图及仿真模型(Air power 270VDC supply system simulink simulation, which includes schematics and simulation models)

简单的脚本来读取视频文件，并跟踪单个二维红色标记使用的色调和饱和度值。最大的红色斑点检测，平均统筹此Blob位置跟踪。这段代码没有任何跟踪内置的：它把每一帧独立。 这是假设是一个常数的视频帧速率视频。由此产生的协调时间序列存储在变量：吨，结晶度和YC。(Simple script to read a video file and track a single red marker in 2D using the hue and saturation values. The largest red blob is detected and the mean co-ordinate position of this blob is tracked. This code does not have any tracking built-in: it treats each frame independently. This assumes that the video is a constant frame rate video. The resulting co-ordinate time series are stored in the variables: t, Xc and Yc.)

matlab中值滤波源代码，对于图像处理的人员有一定的参考意义。。(median filter matlab source code for image processing personnel have some reference value. .)

对3阶滤波器LSL算法的权系数和MSE进行预测(Coefficient and MSE rights of the order filter LSL algorithm to predict)

说明：  遗传算法的实数编码MATLAB程序，不是工具箱，有助于理解遗传算法的编程实现(Genetic algorithm written by maltab)

说明：  QR分解是球形MIMO检测算法必不可少的环节,本代码采用m语言描述了QR分解分解具体怎么实现,而不是直接调用matlab内部函数,采用的是QR分解的脉动阵列结构,据此代码可轻易实现QR分解的FPGA设计(QR decomposition is an essential part of the spherical MIMO detection algorithm, the code uses QR decomposition decomposition m language to describe specifically how to achieve, rather than a direct call matlab internal function, using the QR decomposition systolic array structure, pursuant to which the code can be easily QR decomposition FPGA design)

照书上写的一个小程序，已经测试过没有问题(According to the book written by a small program, no problem has been tested)

2D lifting wavelet transform 的MATLAB实现方法，适合初学者进行学习。(2D lifting wavelet transform MATLAB implementation method, suitable for beginners to learn.)

利用总体最小二乘来实现esprit算法，代码运行过完全可以使用(Achieved using total least squares esprit algorithm, code can use to run over)

求解离散病态问题的正则化方法matlab 工具箱，可以应用到地震勘探中反演问题的求解!(solving discrete pathological problems are based on Matlab toolbox, can be applied to seismic inversion solution!)
