<p>You don’t need to keep track of the order of dimensions or align dimensions
during multiplication.
When you do arithmetic with two arrays,
pyspecdata will first reshape the arrays
so that dimensions with the same names are aligned with each other.

but not the other,
pyspecdata will simply tile the smaller array along the missing dimension(s).</p>
