In a sense Haskell arrays are always one dimensional. But as you noted tuples are used to achieve higher dimensionality. As far as I know there is no way of asking for the dimension of an array. You could write your own class for that though. Here's a suggestion:
\begin{code} dims :: (Ix a, HasDimension a) => Array a b -> Int dims arr = dimension (head (range arr))
with the following correction, it is ok. dims arr = dimension (head (range $ bounds arr)) thanks at lot Fred -- ------------------------------------------------------- Dr. Frederic Nicolier Maitre de conferences, laboratoire LAM - URCA Animateur du projet ANITA : http://f.nicolier.free.fr/recherches/ Dept.
