MATLAB: Sum of rand matrix equal to zero

sum of all is zero

Dear All,

I want to generate matrix A ,i.e. n by n random matrix but the sum(sum(A)) = zero. Help in this regard will be highly appreciated……..

Regards……….

Subtract the mean from the samples:

n=10; z=randn(n,n); z=z-sum(sum(z))/(n*n); sum(sum(z))

Do you mean iteratively in a loop? E.g., changing elements one at a time in column order:

n = numel(A);
for k=1:n
    A(k) = -1;
    % Use A here
end
