Assuming a sparse representation it is about 4 lines of SQL. This is known not least because you can read enough articles and papers that discuss it and it optimises well. The obvious google search does not reveal any corresponding XQuery discussion, neither does it appear to have surfaced on this or the eXist mailing list (allowing for my deficient search skills). For something so "trivial" I thought that was rather strange. Hence I thought it would be prudent to ask before naively embarking on a 600k X 40k matrix multiplication.
