激光光学里的光束通过透镜后光斑，及其能量分布(Laser optics in the beam spot through the lens, and its energy distribution)

这是关于matlab在解微分方程方面的应用，很实用。(This is about solving differential equations matlab in the application, it is practical.)

Matlab 的图像处理函数.......自己编写的中值滤波代码，注意处理图像时的像素不能太高，要不响应时间会延长很多(The Matlab image processing functions ... the median filter code I have written, pay attention to handling image pixel can not be too high, or the response time will be extended)

周期高斯一介导、高斯二介导即高斯脉冲（即UWB信号）的功率谱图像，对应不同的占空比和不同的脉冲形式，随着阶数的增加中心频率右移，频谱也为高斯形式，且随着周期数增多，呈现线谱形式(Cycle Gaussian ordinary derivative, ie the Gaussian two-mediated Gaussian pulse (the UWB signal) of the power spectrum image, corresponding to different pulse duty cycle and a different form, with the increase of the order of the center frequency shifted to the right, the spectrum also Gaussian form, and with the number of cycles increased, showing the form of line spectrum)
