Finding ratio between two elements of one Array

Hi there,

I have an array that looks like this:

Array =

     1     2     3     4     5     6     7     8     9

I would like to find the ratio between two elements in this array. For example 1/2, 2/3, 3,4, 4,5... etc

I came up with this code

ratio = [];
for i = 1:length(Array)
ratio(i) = Array(i)/Array(i+1)
end

but the problem is that the last iteration gives me error (last index +1) :(

how can I overcome this problem. Thank you in advance

Anytime :) , see the other answer which is easier than loop.
