variance for an array

I have a value for the variance and need to assign this value to each component in a 200 component array, is there a way to assign the var to each component in a for loop? thanks in advance

Why would you need a for loop?

V = 42; % you don't tell us what is the variance. So that is my choice. 42 is the answer to all questions, as I have learned

Varray1 = repmat(V,1,200); % One option

Varray2 = V*ones(1,200); % another

Varray3 = V + zeros(1,200); % or this

Varray4 = kron(V,ones(1,200)); % or this

Varray5 = zeros(1,200); Varray5(:) = V; % Or this

Varray6 = linspace(V,0,200) + linspace(0,V,200); % or, if you want a totally silly way

Ok, many of those solutions are pretty silly.

Do you want to bet that I can't come up with at least a dozen solutions, none of which need a loop?
