Matlab实现的全相位频谱分析，可以自行设定点数和输入序列。结果包括频谱图和与普通fft的对比(Matlab to achieve all-phase spectral analysis, can draw up a point and input sequence. The results include the spectral figure and the comparison with ordinary fft)

this code is to realize a RANSAC algorithm

用matlab编写的三维FDTD计算源代码，简洁清楚(three-dimension code of FDTD)

对想做一些关于地震重现规律研究的有用，这是现成的程序源代码，可以直接用。(it is very helpful for some persons who want to do some research on earthquake b value )

some codes for solving linear algebric equations using numerical methods

antennas program and the radiation patterns also available

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.
