If you just wanted to know the repeated values you could use unique to filter each first occurrence, which would leave the repeated values.
As you want to know how often every value occurs the most logical step would be to histcounts. Use max and min to determine the bin edges.

This does not appear to relate to the original question: the probability of a repeated value created by randn() is very low -- you would have to generate more than 1e8 samples for the probability of even one duplicate to reach 50%.
