中文说明： 旋转机械二维全息谱计算的实用例程，可实现对二维数据的聚类，对HARQ系统的吞吐量分析，实现六自由度运动学逆解算法，IMC-PID是利用内模控制原理来对PID参数进行计算，分数阶傅里叶变换计算方面。
English Description：
The practical routine of two-dimensional holographic spectrum calculation of rotating machinery can realize the clustering of two-dimensional data, the throughput analysis of HARQ system, and the six degree of freedom inverse kinematics algorithm. IMC-PID uses the internal model control principle to calculate the PID parameters, and fractional Fourier transform calculation.
