这个是有一个点P(i)=(x(i),y(i)), 要符合complex plan 到点 x(i)+jy(i),j 是想象出来的单位 (j^2 = -1)
现在要写一个函数,用bivariateEMD 在不同的IMF中分解一条线,和,通过整合的IMF重建这条线,并在一张图中显示这些信号。
原文是:(we consider that a point Pi=(xi,yi) correponds in the complex plan to the point xi+jyi where j is the imaginary unit (j^2=-1). write a function that decompose a line in its different IMF using bivariate EMD and reconstructs the line by combining the IMFs.)
这片名叫<Bivariate Empirical Mode Decomposition> ----- Gabriel Rilling, Patrick Flandrin, Fellow, IEEE, Paulo Goncalves, Jonathan M. Lilly
是IEEE SIGNAL PROCESSING LETTERS的
