I have two $2$-column matrixes, one of the has $467$ rows while the other one has $61468$ rows. Both them are trajectory paths of same robot, the big matrix is kind of raw data and the smaller one is filtered data. What's the deal? I have to calculate MSE for these two. How should I make them to have same size? bigger matrix most be smaller by omitting data or I have to add some fake arrays to the smaller matrix to make it bigger?
Off-topic: I have bunch of these matrixes that I have to compare one by one, Does MATLAB or any other app has built in functions for this?
This is an example of my matrixes: (red one is bigger one)
