Create a set of 165 random numbers

Hi all,

I would like to create a set of 165 random numbers within the range of 1:557 so that the radom numbers are distributed equally in groups of 10 numbers. Here is an example, to make my problem more clear:

1:10 --> 3 random numbers (say 3,6,7)

11:20 --> 3 random numbers (say 11,15,18)

21:30 --> 3 random number (say 26,27,28)

.

.

541:550 --> 3 random numbers (say 542,544, 547)

I hope my problem is clear...

All help is appreciated, thanks!

Thank you, I think I got it:

group = (i*10+1):((i*10)+10);

y = randsample(group,3,false)
