Sure, just index using more than two indices.
E.g. m(:,1,1) = vector_1, m(:,2,1) = vector_2 and so on. You can then
do m(:,1,1).*m(:,1,1). You may also be interested in the squeeze
function.
N-d arrays, as they are called, do seem to lose a lot of the benefits
of vectorisation, unfortunately, or they did for me in the past, but
as far as indexing goes, you can think of them as matrices or
higher-order tensors.
