while using the function randi that generate random integers uniformly disterbuted i sometimes get in the output vector the same numbers for example:
4 2 5 3 4 8 7 9 7 4
(the number 4 was three times in the row above)
how can i avoid this?
locTX=randi([1 20],1,4);

rand() and randi() are uniform. randn() is normally/Gaussian distributed. You might want to edit your post (body and subject line) to get rid of randni to avoid confusing people with a function that you say you don't use.
