Generate a random number in a certain range in MATLAB

Question

How can I generate a random number in MATLAB between 13 and 20?

Answer 1

If you need a floating random number between 13 and 20

(20-13).*rand(1) + 13

If you need an integer random number between 13 and 20

floor((21-13).*rand(1) + 13)

Note: Fix problem mentioned in comment "This excludes 20" by replacing 20 with 21
