I have 5 vectors, from which I would like to extract 6 variables that should be i.i.d (Indipendent and Identically Distributed).
I want to extract (following the same uniform randomly distribution) 1 variable from A, from B, from C and from D, and 2 variables from P.
To use the same distribution and have a i.i.d set, I think that I need to use the same random function like 'rand' or 'randi' just one time on the overall vectors, but I do not know how to do it.
Someone can help??
