Uniform Random Number blocks in my simulation model?

Question

I've used 2 Uniform Random Number blocks in my simulation model, but every time I run the program they generate last numbers (exactly the same). I need to test the model with new generated numbers. what should I do? thanks for your helps in advance

Answer 1

This is due to the random seed generator. You're probably using rng that sets a seed. To reset the seed for random number generation each time you launch your script, use

> rng('shuffle')
