matlab中的floyd算法，对数学建模有很大的帮助(floyd algorithm matlab in the mathematical modeling of great help)

tvp-var model 可以用来做TVP-VAR模型(tvp-var model for good use)

本文先简要介绍了矩阵的积分和微分的定义；接着通过弹簧-质量块儿-阻尼器系统的例子，阐述了求解常微分方程数值解的常用方法；最后，在前两部分的基础上，总结了用MATLAB求解形如_X(t) = f(X(t); t) 矩阵微分方程数值解的方法。(In this paper, the definition of integral and differential of matrix is briefly introduced. Then the common method of solving numerical solution of ordinary differential equation is described by the example of spring mass block damper system. Finally, on the basis of the first two parts, the solution of the form of _X is summed up by MATLAB. (T) = f (X (T); t) numerical solution of matrix differential equations.)

说明：  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.

说明：  matlab实现rnn神经网络，对于使用的现场臭氧发生器数据，进行数据建模仿真，用现场数据对神经网络进行训练并得到参数(use matlab finish rnn)

DOA估计的又一经典算法，和MUSIC相比，不需要谱峰搜索，相对更快捷！是利用空间旋转不变性求得波大方向。(DOA estimation is a classical algorithm, and compared to MUSIC, without spectral peak searching, relatively more efficient! Is the use of space rotation invariance to obtain the wave direction.)
