Concise way to compare/find multiple values

If I have a matrix of integers called A and want to find the mask corresponding to values 1 and 7, I currently do this:

mask = (A == 1 | A == 7);

But is there a conciser way of doing this? Something like A == [1 7]. If I have many lookups I'd need to use a for loop or maybe bsxfun. It feels like there should be some simple way I'm missing.

You may try ismember function.

ismember(A,[1 7]);
