Hello,
If I had two vectors x1 and x2. How could I make vector x3 with all the elements of x2 except the first 3 elements and last 3 elements are from x1?
Many thanks
John

Please give a specific title to your questions. Otherwise it's hard to tell wether you're double-posting or not.

Is this what you wanted?
x1=1:10
x2=11:20
y=[x2(3:length(x2)) x1(1:length(x1-3))]

If same size:
x1(4:end-2) = x2(4:end-2);
Otherwise:
[x1(1:3); x2(4:end-2); x1(end-2:end)]

To get all but the last 3, use this:
x1(1:end-3)
You can work out how to get all but the first 3 =)
And you already know how to concatenate vectors.
