values of randi function repeat themselves
显示 更早的评论
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);

Each number occurs exactly once. The numbers themselves are not random. They go from 1 up to some numbers, including every integer in between. Only the location of the numbers is random. So even if you scramble their location, each number still appears only once. By the way, there is no function called randni().

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.
