Random Number Generator is the creation of random numbers without any decision or noticeable patterns among them. How can I generate random alphanumeric strings? From this it follows that all 10 rows of S will also be unique. The loop keeps generating the same random numbers. With a vector of only 100 numbers, several trials (in a loop) have always found equality between the element numbers of the vector and its unique elements, although with enough trials, there are bound to occasionally be repeats. It just occurred to me that the constraint the poster wants to implement is most easily expressed with respect to the diff. ), % Select 10 numbers from 100 to 1e7 without explicitly creating 100:1e7. The main difference between randi and randperm is that randi contains an array of values that can be repeated but randperm contains an array of integers that are unique. The graph of this is normally flat since it is drawn from a uniform distribution. Find the treasures in MATLAB Central and discover how the community can help you!
