Hello! I want to create a vector w1 having the same length as another vector w but containing certain x values. How can I fix the code?

v = [100; 177; 186; 124; 175; 211; 132; 144; 124; 111; 133; 152];
w = [25; 14; 33; 20; 14; 22; 29];
number_w = height(w);
x = randsample(v,1);
% w1 = ?

So we have the values for x, but at which indices do you want to put them in w?

I want to get w1 in the following way:

w1 = [x; x; x; x; x; x; x]; % for example: w1 = [111; 186; 175; 211; 144; 177; 152];
