Indices for Minimum of an Array

[Ken-Cogger]

I have an array A(625,625) with minimum value returned by %minvalue(A).
Is there a simple way of returning the indices for this value?
%minindex(A) does not work even though its argument is said to be an array.

You have to vec and unvec it:

compute ix=%maxindex(%vec(a))
compute col=%block(ix,625)
compute row=%clock(ix,625)

What if array A is packed/lower triangular?
Thanks,
Ken.

Use %SYMMCOL and %SYMMROW instead:

compute ix=%maxindex(%vec(a))
compute col=%symmcol(ix)
compute row=%symmrow(ix)
