Hi guys. How can i randomly generate a vector with 100 elements that contains integers between 40 and 120 than save in a variable P_vec the positions where the elements have values between 50 and 70?

Thank you!

This will give you a logical mask describing the location of elements within the closed interval [50 70]. You can call it what you want.

A = randi([40 120],100,1);
idx_logical = (A>=50) & (A<=70);

While logical indexing is often the more efficient approach, sometimes you might want the actual indices. If you want the linear indices of those locations:

idx_linear = find(idx_logical);
