可以识别二维的条形码。读入条形码图像之后即可处理成相应的数字。但是对图像存储位置有要求，所以请按照程序前面的存储位置放置您的二维图像(Can identify the two-dimensional barcode. Reads the barcode image can be processed into a corresponding digital. But the image storage location requirements, so please be placed in accordance with the storage location of the program in front of the two-dimensional image)

这个是对一般信号进行快速傅里叶分析。并画出其幅频图和相频图。与原信号进行比较(This is the general signal fast Fourier analysis. And draw the amplitude frequency and phase frequency diagram. Comparing with the original signal)

说明：  卡尔曼滤波算法。使用STm32跑的，亲测可以用，效果很好，算法源码(Kalman filtering algorithm.Using STm32 run, pro test can be used, the effect is very good, algorithm source)

用平面波展开法计算二维光子晶体带隙的程序(With the plane wave expansion method for calculation of 2-d photonic crystal program)

本程序是绘制转子振动轴心轨迹的实验程序。 主要功能是进行绘制转子的轴心轨迹。(This procedure is the experimental procedure for drawing the axis of the rotor vibration axis. The main function is to draw the axis of the rotor track.)
