中文说明：信号处理中的旋转不变子空间法，调试通过可以使用，采用偏最小二乘法，处理信号的时频分析，这个有中文注释，看得明白，计算加权加速度。
English Description：
Signal processing in the rotation invariant subspace method, debugging can be used, using the partial least squares method, the time-frequency analysis of the signal processing, this has the Chinese notes, see understand, calculate the weighted acceleration.
