Hi all,
I have a vector [1x24] and I would like to add 2 extra elements every 4 elements, so the new vector will be [1x32].
The two extra elements will be the first two number of the first group pf 4 numbers, an example:
vector_1=[ 1 2 4 5 7 8 9 3......]
Vector_2=[1 2 4 5 1 2 7 8 9 3 7 8.....]
thanks in advance
Nikolas

temp = reshape(vector_1, 4, []);
temp = [temp; temp(1:2,:)];
Vector_2 = reshape(temp, 1, []);
