Advanced use of randi(x) and other random number generating functions

2 Ansichten (letzte 30 Tage)
Is it possible to get the randi(x) function to work with a specifically chosen set of numbers, such as 1 through 9 except 6?
From what I can tell, the function description doesn't make it seem possible. Is there a creative way around this? What about using other random number generating functions?

There's nothing builtin do exclude certain numbers. Of course this is accomplished with a little bit of manipulation:
x=randi(8,[5 5])
x(x>=6) = x(x>=6)+1
randperm might be your friend as well.

your_range=[1:5 7:9]
[~,ii]=sort(rand(1,numel(your_range)))
out=your_range(ii)

The sort(x) function became very important later. Thank you for pointing it out!
