I have a group of matrices that should belong to 3 different groups. I know which matrices should belong together in a group. I want to show that is actually is the case by clustering them, and seeing how they nicely separate into these groups. I am using matlab, and I would like to give it the complete set of matrices, and get back a vector or some data structure telling me which matrices are in which group. I am flexible on the type of algorithm/model/method used. I think PCA and k-means would be a preference. |
