非连续波导时间域有限差分法仿真（TD-FDM），入射波为理想高斯脉冲。经典之处在于利用matlab制作了电影文件，可以动画形式看到波的入射、反射以及透射状况。(Non-consecutive time waveguide FDTD simulation (TD-FDM), for an ideal Gaussian pulse incident. Classic is the use of matlab has produced a movie file, you can see an animation sequence of the incident wave, reflection and transmission status.)

最小方差恢复算法，用于恢复图像中未知位置的点像素(Minimum variance recovery algorithm, used to restore the image point of the unknown location of the pixel)

A biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. Iris recognition is a part of the biometric identification methodologies which also include facial, fingerprint, palm and many other biological traits. They all offer new solutions for person identification, authentication and security. Currently users have to carry security badges or know certain pin/pass codes in order to get into secure zones or to log into a computer. In this paper we propose an algorithm for iris recognition, which can be applied in real time with standard webcam and with good matching result.

说明：  惯性导航的一些资料，互相学习，互相借鉴一下。(Inertial navigation of some of the material, learn from each other and to be drawn lessons from each other. )

一个好用的鸡群算法程序，供新手学习使用，可在网上找相关资料(A good CSO program,for beginners to learn and use,,you can find relevant information online.)

在matlab中，实现图像旋转（两种方法：临近法、双线性法）(In matlab, the realization of image rotation (two methods: near the bilinear method))

Detection of Iris with segmentation and dilatation, Not performant algorithm, better with hough transform

说明：  lda是一个集合概率模型，主要用于处理离散的数据集合，目前主要用在数据挖掘（dm）中的text mining和自然语言处理中，主要是用来降低维度的(lda is a set of probability models, mainly for dealing with discrete data sets, the key used in data mining (dm) in the text mining and natural language processing, is mainly used to reduce dimension)
