I'm thinking, given that the phase map was produced by applying
Base.angle() on another (complex) matrix (say we call it M), it is this
function which caused the phase wrapping in the first place, right? So
can't I somehow get around the problem and produce the unwrapped map
directly from M?

Sorry, perhaps I did not explain myself :)
One can see the phase oscillates between -\pi and \pi.
I would like to compute how many times the phase changes by 2\pi as one
goes around the origin.

I guess what I'm trying to say is that your answer makes sense for
continuous functions, while mine has jumps of 2\pi, and so the phase change
is equal to the total number of these jumps (times 2\pi). Does this make
sense?

Wouldn't the answer depend on the path you choose?

I'm hoping it wouldn't, but it is actually one of the things I would like
to test.

javascript:
It seems you want to unwrap the phase (plus pi) along your path:

But as you data are quite discrete, I'm not sure it will work. Maybe if you
interpolate.

Seems like
totalchangeinphase(m,n) = 0
would work and be very efficient. (As you described
