Hi, I need create a code where the elements of an array are repeat:
For example:
% Create a simple vector:
for i =1:4
Vec(i) = i;
end
Vec = [1,2,3,4];
If I need repeat the elements of this vector 2 times:
Vec = [1,1,2,2,3,3,4,4];
3 times:
Vec = [1,1,1,2,2,2,3,3,3,4,4,4];
I know using the function: repelem; I can get this result but I need do it using a for loop/while.
¿Any idea?

I'd do it slightly differently:
Vec = 1 : 4;
n = 3; % Number of times to repeat each element of Vec
Vec2 = zeros(1, 2 * length(Vec));
for k = 1 : length(Vec)
index1 = (k-1) * n + 1;
index2 = index1 + n - 1;
Vec2(index1 : index2) = Vec(k);
end
Vec2
