    _______________________________________________________

Details:

accumarray() does not handle an empty list of subscripts. Example:


>> accumarray (zeros (0, 1), zeros (0, 1), [0 1] , @(x) {x})
error: accumarray: subscript indices must be either positive integers less
than 2^31 or logicals


I would expect to get back an empty matrix.
