Simple array step sizing.

I know this is probably easy to code but my mind just isn't running on all cylinders today. I need an array of given size to decrease by a half each element (eg: 1, 0.5, 0.25, 0.125, 0.0625 etc.). Thanks for the help!

One way:

N = 6;
0.5.^(0:N)

Hi,

I need to define a variable B(j)) in the half step. e.g i have the variables A(i) and B(j). So the loops are( for i =2:N and j=2:N .

And B(j)=A(i+1)-A(i)
