中文说明：计算互信息非常有用的一组程序,旋转机械二维全息谱计算，使用混沌与分形分析的例程，基于负熵最大的独立分量分析，独立成分分析算法降低原始数据噪声，实现串口的数据采集。
English Description：
Calculation of mutual information is very useful for a set of procedures, rotating machinery two-dimensional holographic spectrum calculation, using chaotic and fractal analysis routines, based on maximum entropy of independent component analysis, independent component analysis algorithm reduces the raw data noise and realize the serial port data acquisition.
