Witryna% IMF = EMD(X) where X is a real vector computes the Empirical Mode % Decomposition [1] of X, resulting in a matrix IMF containing 1 IMF per row, the % last one being the residue. Witryna10 kwi 2024 · First, the eigenmode function (IMF) is obtained after EMD decomposition, and the energy entropy of each IMF component is calculated . Then, the feature vector is selected. The frequencies of different-order IMF components differ, and the higher the IMF order, the fewer high-frequency components it contains, as shown in Figure 8. … shirley allum ltd
