Answer 1

[Andrei Bobrov]

k = [5 9 11];
ii = randi([1,3],10,6); % [10,6] - size of your array
out = k(ii);

If you have the Statistics Toolbox then randsample()

Otherwise:

specific_numbers = [5, 9, 11];
array_size = [48,93];   %for example
rand_array = specific_numbers( randi(length(specific_numbers), array_size) );

This presumes equal probability for the samples.
