仿真图是速度、距离、幅度三维图像，进行波形数据分析,PLS部分最小二乘工具箱,是学习PCA特征提取的很好的学习资料，能量熵的计算，真的是一个好程序。- FIG simulation speed, distance, amplitude three-dimensional image, Waveform data analysis, PLS PLS toolbox, Is a good learning materials to learn PCA feature extraction, Energy entropy calculation, Really is a good program.
