Not that I really know what I'm talking about here, but this sounds
highly parallelizable. It seems like you could do N/2 measurements at a
time, so this should be O(N) to compute the matrix (ignoring issues of
how long it takes to write the data to memory, but that should be
insignificant).

Even if you can't parallelize it all the way, it ought to at least help.
