均匀介质二维声波数值模拟，采用clayton-engquist 1阶边界条件。有公式及参考文献。带有速度模型以及雷克子波函数，解压后直接运行就可以(2D acoustic numerical simulation of a homogeneous medium, using the clayton-engquist 1-order boundary conditions. Formulas and references. With the velocity model and the the Ricker wave function, and can run directly after decompression)

在matlab中进行曲线修改曲线类型的m函数.比较实用，给大家分享！(Matlab curve in the curve of the type of modified m function. More practical to share with you!)

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.

matlab生成随机数，uinform产生一组[0，1]分布的随机数，riddling产生一个N(0,1)正态分布随机数，normal产生n个N(a,b)正态分布随机数。(Use matlab to generate random numbers, uinform produce a set of [0,1] random number distribution, riddling produce a N (0,1) normally distributed random numbers, normal generate n N (a, b) normally distributed random numbers.)
