Hi
Can I change the lower bound of an array. E.g can I have an array with starting index 0?
Atm
ex(0)=2
Will not work
Thanks for any suggestions!, and have a nice weekend :-)

Example: y(n)=n^2+1 and you want to start from 0
for n=0:10
y(n+1)=n^2+1
end
% y(1) correspond to index 0

You can also use
y=@(n) n.^2+1
y(0:10)

I believe with a huge amount of work overloading some of the key functions (e.g., subsref and subsasgn) you can probably achieve a pretty seamless re-indexing interface. That said, even if it was easy, DO NOT DO IT. MATLAB uses 1-based indexing. Get used to it.
