On-Line Digit Recognition using Off-Line Features

利用函式做種子變數,用種子跑數值,計算其座落區間,最後利用matlab畫出exponential distribution(Function for seed variables, run with seed value, to calculate the located range, the last use of matlab to draw the exponential distribution.)

计算超混沌Rossler吸引子的Lyapunov指数(calculated hyperchaotic Rossler attractor of Lyapunov exponent)

matlab 文件，用于学习m文件，解释m文件的编写及用法(matlab documentation, for learning m paper explaining the preparation of the document m and usage)

power flow analysis using newton raphson method

he modeling equation of this system is MD2X+bDX+kX = F The transfer function between the displacement X(s) and the input F(s) then becomes X(s) / F(s) = 1 / (Ms2 + bs +k)

说明：  轨道交通牵引供电的一个初步模型，给分析暂态一个很好的方向。(A preliminary model of traction power supply for rail transit provides a good direction for transient analysis.)

Carrier frequency offset estimation

直流潮流计算程序（作者FX）提供7种控制方式，导纳矩阵形成有部分问题，小弟只是想学习学习高手的源代码，代码冗杂请见谅(the code of DC—powerflow caculation by FX provide 7 kind of controll mode，but there are some problems in the formation of Y matrix.please let me download some code by good operator )

要求设计一个基于颜色直方图的图像检索系统。该系统能够实现对图像的检索功能，例如，在一万幅图像中搜索出与检索图像相似的图像，依相似程度的大小显示出来。最后用查全率和查准率对系统进行评估。(To design a color histogram based image retrieval system. The system can realize the image search function, for example, a square image search and retrieval of an image similar to the image size according to the degree of similarity is displayed. Finally, recall and precision to evaluate the system.)
