MATLAB: Uniform Distribution (Continuous) fit on data

Question

Hi,

i have a variable 1 <B< 8 ,which i want to pick up randomly each time 1 number(B also could be 1 and 8), (which each value has the same probability of occurrence)so how could i produce uniformly random number between 1 and 8 ??

Answer 1

from: http://www.mathworks.com/help/techdoc/ref/rand.html

Generate values from the uniform distribution on the interval [a, b]:

 r = a + (b-a).*rand(100,1);

or if you'd want the numbers to be integers,

Use the randi function, instead of rand, to generate integer values from the uniform distribution on the set 1:100:

 r = randi(100,1,5);

Although you must note that these numbers are pseudorandom, in that no computer system can in reality generate purely random numbers!
