how do I replace zeros

• x = zeros(1,17); % this is my initial vector of zeros
• x = round(200 + (400-200).*rand(1,16)); % this is my generation of random numbers between 200 and 400
• sum(x); % this is my sum of my randomly generated numbers

How do I replace the zeros in my initial vector with the 1x16 vector that I generated, and and it with the sum, creating a final 1x17 vector?

Address 16 of the elements of ‘x’:

x = zeros(1,17); % this is my initial vector of zeros
x(1:16) = round(200 + (400-200).*rand(1,16)); % this is my generation of random numbers between 200 and 400
sx = sum(x); % this is my sum of my randomly generated numbers
