 I want the matrix to be over a different field (i.e. - not the real
 numbers). In my particular case, I want it to be over Z2 (zero and one).

The top results of a search for Finite Field library look promising.

Re: PCIe card not appearing when in slot #2 on a certain brand of Dell machines

[Yaacov Weiss]

2012/1/24 Shachar Shemesh shac...@shemesh.biz:
 I know, the subject is strange, but the truth is that the actual problem is
 also strange.

 At work, we have a batch of Dell machines. We also, regularly, use a certain
 type of PCI-express x1 card for video capture and playback. Strangely, on
 those machines, if we insert the card into slot 2 of the machine, the card
 is not visible to the kernel. It does not appear on lspci, and obviously,
 the driver is not loaded and does not work. Moving the card to a different
 slot resolves all of the above problems. The machine's BIOS has an option to
 enumerate all cards, and does see the card without a problem.

 The problem happens with Fedora Core 15, and happened on at least three
 different machines, so we can rule out a machine failure.

 I am at a loss as to how to even begin to debug this problem.

I would probably begin by checking if some other type of card works
in slot 2, and if these cards work in slot 2 using different distributions
and/or kernel versions.
