In the Arabian Nights, there are many tales involving castles with locked
doors. Behind each door is an unexpected world more intriguing than the
last. Well, J is like that. I am standing in awe before the latest door
labelled Special Codes.

Hi Ric,
Thanks for the code. But I did not quite comprehend the phrase "special
code". Do you mean that the hook (i. <./) gets replaced by some low level C
code, instead of being parsed as a general hook?

You could also use
argminall=: 4 $. $.@(= <./@,)
However because neither take advantage of the special code (i. <. /), they
don't have the same performance.

Adding to Henry's idiom :
argminall =: $ #: I.@(= <./)@,
argminall 3 3$5

This is a standard APL idiom.

Dear all,
I want to find the position (i,j) of the min entry in a n by n matrix.
My current solution is
((=<./),mat )#"1 2,/(i.n),"0/i.n
Is there a smarter method?
