%How can i create this vector? Please I need your help.

    Vector = [1 1 1 1 1 0 0 2 2 2 2 2 0 0 3 3 3 3 3 ...];

What pattern do you want? I see 1 block of 1s, 3 blocks of 2s, so you want 5/6 blocks of 3s?

Sorry, it was a mistake. Thanks

Answer 1

B = 1:50;
Vector = repelem(B, 7);
D = 0;
for j = 1:size(Vector)
    D = D +1;
    if (mod(D, 7) == 0 || mod(D, 7)==6)
        Vector(j) = 0;
    end
end

Simpler:

V = repelem(1:50,7);
V(6:7:end) = 0;
V(7:7:end) = 0;

Some notes about your answer:

• Transposing the vector on every single loop iteration serves no purpose.
• The variable D just replicates the value of j, so is superfluous.
• linspace(1, A, A) is just 1:A.

Answer 3

Simple use of repelem and basic MATLAB indexing:

V = repelem(1:50,7);
V(6:7:end) = 0;
V(7:7:end) = 0;

Or for older MATLAB versions:

V = repmat(1:50,7,1);
V(6:7,:) = 0;
V = reshape(V,1,[]);
