is there any better way to write this in MATLAB ?

if (binNumber2 == 0)
   binNumber2 = 1;
end

There are several ways of doing things like this. It also depends what you want to do if binNumber2 is not zero, can have other values than 0 or 1, and whether it is an array or not.

A = true, A = ~A,
B = 1, B = 1-B
C = [0 11 12 13 14], C(C==0) = 1
etc.

And of course these methods apply if and only if the numbers are
integers.
If the numbers are floating point, then these methods don't work at
all.

No.

You can mask the statement in a depressingly large number
of guises, but at the end of the day, your statement above
is what actually happens.
