how can i generate this chromosome?

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. It is work perfectly.

how can I use this chromosome in population. for example if I want to find 100 chromosome.

hy, try this:

chrom=randi([1,3],1,9)

[ghazwan alsoufi]

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]

[isuru senevirathne]

chrom=randi([1,10],1,9)

you can not make to repeat each number in three times , becuse it is randomly generate
