Webb10 sep. 2024 · 1. Well, if you need uniformly distributed random numbers, then rand is better. If you need normally distributed numbers, randn is better. They're different tools for different jobs. It's kind of like asking which is better, a hammer or a screwdriver; it depends on whether you need to drive a nail or a screw. – Ilmari Karonen. WebbHello, How to generate random integers with a seed value. I know about randi and ranperm. rnadi can use a seed value to generate random integers but the problem is repetition.

WebbUse the rand, randn, and randi functions to create sequences of pseudorandom numbers, and the randperm function to create a vector of randomly permuted integers. Use the rng function to control the repeatability of your results. Use the RandStream class when you need more advanced control over random number generation. Funktionen alle erweitern
