Language

to read the image and crop the specified area to convert RGB image next to convert gray scale image to find the histogram equalization

说明：  matlab 矩量法编程啊 不错的东西 可以看看啊啊 (method of moments matlab programming ah ah ah good things to look at)

使用matlab编程环境实现同态信号的滤波处理，同态滤波算法(Matlab programming environment used to achieve the filtering Homomorphic signal processing, homomorphic filtering algorithm)

One of the most advanced routines in picture editing. Remove undesirable parts from pictures.

永磁同步电机的MATLAB模型,Clark变换，park变换仿真，及其逆变换 同步旋转坐标系下的数学建模 精致坐标下的数学建模(MATLAB model, Clark transform, park transform simulation and inverse transformation of permanent magnet synchronous motor (PMSM). Mathematical modeling in synchronous rotating coordinate system Mathematical modeling in refined coordinates)

说明：  对周期激振力作用下的单自由度无阻尼系统，将激励展开成傅里叶级数，观察其对方波函数的逼近情况，并计算系统的受迫振动。(For the single degree of freedom undamped system under the action of the periodic excitation force, the excitation is expanded into Fourier series, and the approximation of Fang Bo's function is observed and the forced vibration of the system is calculated.)
