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.

用于阵列信号处理之中实现多重信号分类，即music方法和Esprit方法。(music and esprit )

在共梯度法中 只有当初值的选取靠近最优解时 迭代才会收敛 当远离时发散 且 当精度控制为0.1时可以实现 但设为0.01时就实现不了(numeberica method)

自己做的一个室内无线通信仿真，内有说明文档，图形界面控制，十分生动(themselves do a simulation of indoor wireless communications, has documentation, graphical interface control, a very lively)

说明：  在MATLAB环境下，实现模糊控制，在必要的地方都有注释，适合研究模糊控制(In the MATLAB environment, fuzzy control, where necessary, have the notes for the fuzzy control)
