通过均值滤波、高斯滤波等实现图像平滑处理，使用MATLAB编程，完全无错能跑。(Image smoothing by mean filtering, Gaussian filtering achieved using MATLAB programming, completely error-free run.)

simulink_labs，，运动建模和仿真用的，matlab的工具箱之一，，，要需要的拿去，，(simulink_labs,, modeling and simulation exercise used, matlab toolbox of one, to take the necessary,,)

电力系统发生三相对称短路时用MATLAB进行潮流计算，计算短路电流和短路电压(Symmetrical three-phase short circuit occurs, the power system with MATLAB for flow calculation, calculation of short-circuit current and short-circuit voltage)

将Quaternion四元素坐标系转换为一般的欧拉角坐标系，避免采用反三角函数导致的值域限制问题。参数xi为搜索的精度，对于每个欧拉角可以分别设定，xi越小，搜索越精确。(Quaternion quaternion coordinate system will be converted to general Euler angle coordinate system, avoiding the use of inverse trigonometric functions due to range limitations. The accuracy of the search parameter xi, for each Euler angle can be set separately, xi smaller, more accurate search.)
