Well, it's deliberate and documented.
R sorts complex numbers by real part then by imaginary part. Matlab,
according to its documentation, sorts by modulus then phase.
There isn't a unique way to sort complex numbers, so you're going to get
differences. Personally, I think the R method is more straightforward,
since you don't need to decide and remember where the branch cut goes on
the phase coordinate.
