[Gretl-devel] Re: making matrix functions applicable to matrix arrays

Hi all,
I just thought it might be nice to extend the scope of some functions
we have. Take rows(), which returns a scalar. Why not have it return a
vector when applied to a matrix array? Of course the same could be
done with cols().
In principle I agree. (Although perhaps the usefulness of determining
all the row numbers of a bunch of matrices is debatable, but who knows.)
OTOH, there's a related idea about dealing with all array elements in
one go in this ticket:
https://sourceforge.net/p/gretl/feature-requests/160/ ("apply() function
built-in for elementwise operation"), and there the last entry is that
we said it's not top priority...
cheers
