how can i generate this chromosome? I tried to generate randomly this chromosome [2 2 3 1 2 3 1 1 3]. this chromosome represents that I have 3 jobs and each job has 3 tasks. I need this chromosome to use genetic algorithm.

I would start by creating an array containing the numbers you want in it and then using randperm to generate a random random order.
Numjobs = 3;
NumTask = 3;
chromosome = repmat(1:NumTask,Numjobs,1);
order = randperm(NumTask*Numjobs);
chromosome = chromosome(order)

Thank you very much for your answer. But I need to repeat each number three times like [1 2 1 3 2 2 3 1 3]
