So does Kraus. See page 461 in the 3rd edition of "Antennas".

I don't have the third edition, but the explanation of MOM first
appeared in the second edition which I do have. It's a very clear and
concise explanation of the method. I highly recommend it for anyone
wanting a basic understanding of how NEC and MININEC based modeling
programs work but not needing the very detailed mathematical treatment
of the NEC or MININEC manual.
