@Wezl Scala: m=>m.size==m(0).size if matrix input assumed
In APL, =/⍴ would probably work (also works for higher dimensions)
Not super interesting if matrix input is assumed
If matrix input isn't assumed, m=>(m++m.transpose map(_.size)toSet).size<2 might work
And here's some more antifreeze for good measure
Starting to get cold again here even though it's summer, so you can never be too careful
