Hi I am trying to divide one array into 3 arrays
let's say A = [11 22 33 44 55 66 77 88 99]
I want to divide A like this:
B = [11 33 55 77]
C = [22 44 66 88]
D = [99]
This is just an example...Could you come up some idea for this?

>> A = [11,22,33,44,55,66,77,88,99];
>> B = A(1:2:end-1)
B = 11 33 55 77
>> C = A(2:2:end-1)
C = 22 44 66 88
>> D = A(end)
D = 99

A simple way is by indexing, like so:
A = [11 22 33 44 55 66 77 88 99];
B = A([1, 3, 5, 7]);
C = A([2, 4, 6, 8]);
D = A(9);
If you are looking for a more general solution than explicit indexing, then you will have to provide more parameters for your problem.

If you wanted to filter by even and odd, then you should have specified that in your question. That operation is not difficult though, see Stephen Cobeldick's answer.
