分裂场PML吸收层，模拟时谐场，在二维空间的传播。(split PML to simulate the sinsoudal wave )

说明：  根据风速公式在SIMULINK环境中搭建的阵风风速的模型，可运行(According to the formula in the SIMULINK environment wind gust wind speed model to build, run)

基于matlab的小程序，用于生成移动的正弦波。对其他基于matlab的视频制作和动画设计也有一定的借鉴意义。(a matlab code for generating moving sine wave, and may be useful for other video-making or design on the matla platform.)

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.

matlab的数理统计工具箱，有很强的实用价值，适合当做应用学习库来进行保留(Matlab statistics toolbox, has a strong practical value, suitable for application to retain as learning library)

计算时间信号序列的谐波总畸变率，同时课计算基波的幅值和相位，典型应用于电力信号分析。(The total harmonic distortion signal sequence computation time, while computing the fundamental lesson of the amplitude and phase of the signal analysis is applied to a typical power.)

说明：  无传感器永磁同步电机matlab仿真 pid自适应 已调的还可以(Sensorless permanent magnet synchronous motor adaptive pid matlab simulation has been adjusted, they can still)
