Where are you stuck? What have you tried?

.

EDIT In response to your comment...

IF statements don't select out portions of an array like that. You will need an index to do that. Here are some clues, copy and paste into MATLAB:

x = 1:10
idx = mod(x,2)==1  % This is a logical index.
x(idx)
x(~idx)

i've try this so far but its not working..

x=1:1:100;

if a=2*x+1 %odds

a*2

else b=2*x %evens

b^2

end

I've got it. Thank you very much!!
