Matlab does not support an index of zero in arrays (in my opinion, this is the single greatest drawback/mistake of matlab).
In many cases, indexing down to zero is extremely convenient, such as when modeling the addressing of a memory. In these cases, I recommend calculating addresses as normal, and then adding "+1" whenever reading or writing the memory, for example:
addr = ....; b = mem(addr+1) * 2; mem(addr+1) = c + d;
