But, we'll pretend that they are random for now, and address the details later. Just change the values of 99,1,1 to your min and max to get your #s. If you use 99 as your max, randomly 99 + 1 will make the code generate 100, so if you really want max of 99, use 98 in this code. any simple solution. I need the probability of getting zeros less than 0.2. matlab probability. 8 Add a d8 Roll a d8. Hi, I want to generate random time steps to test my function. Vote.
