@notjack I decided to use the Matlab names - and the same argument order as them. I tend to think of them as operators (A . mldivide . B) and (B . mrdivide . A) so the argument order fits that perspective. Wrt to naming - I have attempted to use the same names as in Matlab/Numpy/Scipy. They aren’t Rackety - but are hopefully more familiar. It also has the added benefit that porting other code to Racket will be easier.

abbreviations are frustrating, but I can totally understand the benefits of using the same names as an existing well-known ecosystem

Is mrdivide a friend of mred?
