integer range is [ IRANGE(1), IRANGE(2)]. OUT = RANDINT(M,N,IRANGE,STATE) causes RAND to use the generator determined by the ‘state’ method, and initializes the state of that generator using the value of STATE. Examples:
where specified range is [a b] --- Please note: There are lots of ways to do this and lots of interesting submissions on FEX which provide similar results (see below). random numbers: #18443 - Random Integer Generator #5346 - MYRANDINT -- Random Integer Generation #2...

Hi everyone, I'd like to know how to generate a set of random numbers with normal distribution (randn) belonging to a range defined by me. To make it easier: I want to generate 10 random numbers between [-0.5 0.5] using randn. Thanks for your attention...
