Hi! Your code is very impressive and useful! I am about to learn it and may reference it in the future. So I am wondering is there any paper published or tutorial released in somewhere? Thank you!!

Sorry for the super late reply, didn't ever see this. Unfortunately I don't have any other related materials. This method is a pretty common way of dealing with large matrices though. You can find the math formulas easily. Keyword is block matrix multiplication.
