How to store n iterations of randomly generated matrices

To whom may be able to provide help,

Below is an algorithm that computes randomly generated matrices (of size 3x3). The values of the main diagonal are generated randomly, while the non-diagonal values are zero (as intentionally set). My goal is to store n randomly generated matrices in an array so that I may later plot them . How can I achieve this? The code as I have set-up gives me all zero matrices except the last iteration.

n = 10 ;

bounds = [1 100] ; %interval over which the random number generator will produce values

for i = 1:n

randA = diag(diag(randi(bounds, 3,3)))

randA_all(:,:,n) = randA

end

n = 10 ;
bounds = [1 100] ; %interval over which the random number generator will produce values
randA = zeros(3,3);
randA_all = zeros(3,3,n);
for i = 1:n
  randA = diag(diag(randi(bounds, 3,3)));
  randA_all(:,:,i) = randA;
end
