Actually, that C operator is not exactly equivalent to that sequence of
if/else statements. C has some complexities having to do with the type
of the expression, so there can be some implicit type-casting going on
that is not accounted for in your if/else version.

In any case, we have discussed this matter before, and there are some
things that you can do in Matlab that are similar to the :? operator,
but you start getting into function handles, and start needing nested
functions if you want to duplicate the effect of expr2 or expr3 having
side-effects. And there are some semantics you just can't duplicate at
all because of the copy-on-write semantics of matlab...
