I'm not sure APL2 counts, but you get DOMAIN ERROR on quad-divide for any
'wide' matrix (and I tried several).

Can someone with access to an ISO standard APL
(say Dyalog APL) tell me whether the monad matrix
inverse (domino) gives a result on wide matrices?
The following expression should either always
signal an error, or nearly always produce 13 7
{rho} {domino} ? 7 13 {rho} 1e6
Execute the expression at least twice in case we are
extremely unlucky with the random numbers.
