用于partial least square 算法中数据的训练，并得到相应的系数矩阵(Partial least square algorithm for training data and corresponding coefficient matrix)

用JACOBI迭代法求解线性代数方程组，此迭代法是数值计算基本方法之一。(Use JACOBI iterative method for solving linear algebraic equations, and this iteration method is one of the basic method of numerical calculation.)

匹配滤波器（自己写的随机信号作业，凑合着还算够用吧）(matched filter (himself wrote the random signal operations, make do with it fairly enough))

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.

语音信号处理中，高通滤波器的设计，实现效果比较好的(Speech signal processing, high-pass filter design, to achieve better results)

通过改变不同的频率，实现了使用Matlab播放音乐，因为示例为两只老虎和天空之城(By changing different frequencies, implemented using the Matlab play music, because the sample of two tigers and the Sky City)
