MATLAB code for PCA and K-Means to be applied on Intrinsic Mode Function graphs?

26 views (last 30 days)
I am working on a project in which I need to observe the readings of a sensor, then pass them through a Low pass filter and carry out empirical mode decomposition on the results. By doing this I have obtained large number of IMFs (Intrinsic Mode Functions). Now I need to perform Principal Component Analysis (PCA) and K-means on the graphs of the IMFs. Can anybody suggest the code for PCA and Kmeans in MATLAB that can be applied on the obtained IMF plots.

I found a MATLAB code on the Mathworks site for applying k-means on the gray or color images. I have attached it below. Will it be useful for my project?
