Sorting Complex Numbers

Following on from the discussion re minima and maxima of various Mathcad data types, I gave up on trying to fault-find my original (messy) complex sort worksheet, and present the following simplified Mathcad Prime 11 version for your edification.  It's based on merge sort.

zv is the complex-valued vector to sort, and I've rerun the results in MATLAB.
