Hello all, I have a vector which has the dimensions of 144x1. The numbers in the vector repeat after every sixth row. For example, Vector x = [1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 4 5 6...]';. Now I need to generate another Vector y = [3 7 11 3 7 11 3 7 11...]'; from the Vector x which has the dimensions of 72x1.
Do I need to use a for loop or is there any MATLAB command which will give me this result?
Thank you.
