Arranging even and odd numbers
Posted:

I have a vector x=[0 1 2 3 4 5 6 7] and I want to creat x' from x such that x'=[0 2 4 6 1 3 5 7] This can be achieved by following transformation A*x=x'
where
A=[1 0 0 0 0 0 0 0; 0 0 1 0 0 0 0 0; 0 0 0 0 1 0 0 0; 0 0 0 0 0 0 1 0; 0 1 0 0 0 0 0 0; 0 0 0 1 0 0 0 0; 0 0 0 0 0 1 0 0; 0 0 0 0 0 0 0 1]
How can I generate matrix A without getting into for loops.
