数学建模2008年D题.该文件是2008年全国研究生数学建模D题的求解软件包。(Mathematical Modeling 2008 D. This document is the solving package of 2008 National Graduate D mathematical modeling problem.)

Simulation of the Lorenz Model for Convecting Fluids. Plots X(t),Y(t),Z(t) and the state space trajectory for given initial values, control parameter (r).

说明：  直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)

离散坐标法解辐射传递方程的SRPAN离散程序(Discrete ordinates method for solving radiative transfer equation SRPAN discrete program)

关于matlab的一些知识，希望对大家有用。(Some knowledge on matlab, I hope to be useful.)

说明：  Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.
