Hi

randperm is for permutations WITHOUT repetition. I would need it WITH repetition. I could calculate all permutations (I found some scripts), but I need it for vectors with more than 2000 elements. Any ideas?

Thanks so much

Claudia

在 MATLAB Online 中打开

Try this

randomNumbers = randi(highestNumber, rows, columns);

plug in whatever values you want, for example:

randomNumbers = randi(9, 1, 2000); % 2000 numbers in the range 1-9.

Perfect! I have seen randi but must have been 'blind' as I did not realize that this is exactly what I am looking for. Thanks so much for your fast help! Cheers
