[ale] Using giant matrix in Matlab

[Rev. Johnny Healey]

Well, if each element is a boolean value, then we'll only need 1/8th of the
storage.

For 22,267^8 elements, that's a great question.

60435716178376869169877709157801441 elements, even if each is
represented by a single byte, requires 53677698888756059476 PiB
(pebibytes, old-school petabytes) of storage.

Google says the world population is 6692030277 now.  If everybody on
Earth had 8021138080 PiB of data storage, together we could store
that matrix.  ;)

Seriously, though.  I doubt my own math.  This takes hugeness to
another level.  Twenty two thousand plus raised to the eighth power
seems intractably large.
