Hi
How can I generate a random decimal number inbetween a range of 0 and 0.5 (i.e. 0, 0.1, 0.2, 0.3, 0.4, 0.5)?

I'm not sure what you're asking. Do you want one random number in a range 0-0.5 like you'd get from
r=0.5*rand()
or do you want to pick a number at random from that list of 6 predefined numbers you listed? Or something other than those two options?

>> V = 0:0.1:0.5; % define the numbers
>> V(randi([1,numel(V)]))
ans =
0.4
>> V(randi([1,numel(V)]))
ans =
0.2
>> V(randi([1,numel(V)]))
ans =
0.5
>> V(randi([1,numel(V)]))
