Units seem to be interfering with elementwise square roots. I have with(Units[Standard]): in my .mapleprofile since I frequently use units. I am working on a document which uses units but also requires computing the elementwise square root of a 2x1 vector.
If I boil this down to the very simple document attached, you can see that the units package is somehow interfering with the square root of a vector of numbers without units, but doing an elementwise square root doesn't work either. I have tried removing the with(Units[Standard]): line in the startup file for this document and recomputing, but nothing changes.
I don't see how to do elementwise square roots in this situation. Is there a workaround, or am I missing something?
