how to create 2 vectors from a matrix

hello all,

I have a matrix called harm and I would like to create 2 vectors from that matrix, harmx and harmy. harmx would have the components i=1,3,5....39 while harmy will have i = 2,4,6...40.

I tried that, but it said that the Index exceeds the matrix dimensions

 harmx []
 harmy []

 for i=1:40

    if mod(i,2) == 0
        harmx = harm(i);
    else 
        harmy = harm(i);
    end

 end

Thank you in advance!

In your case, harm is not a matrix, it's a vector

harmx=harm(1:3:end)
harmy=harm(2:2end)
