Correct way of using random number generator with multiple m files
4 views (last 30 days)
Dear MATLAB community,
I am using random functions like randi and rand in two functions in two different m files. These two m files with the random function is called from a main script. I would like to use random number generator rng to seed the random function. Do I use the rng at the main script or do I use it separately on the m files, which is the more proper way?

It depends on the reason you are setting the seed.
Do you want the two functions to be using the same set of pseudorandom numbers? Then set the seed in both function files.
Or do you want the two functions to be using different pseudorandom numbers? Then set the seed in the main function.
