MATLAB: Makedist discrete uniform distribution

makedist

Hi all

I am trying to create a uniform discrete distribution, with 5 values (20% probability each), by using makedist command

However, I am bit confused with the boundaries.

My values I want to be : 20,25,30,35,40

Can you please help?

thanks

Nikolas

It appears that MATLAB will only give you random integers 1..K for any K you want, so you will have to convert those to your desired values, e.g.:

myrandoms = 15 + randi(5,100,1)*5  % A vector of 100 random numbers from your set

One possible solution would be like this:

A = [50,20,30; 55,25,35; 60,30,40];
[p1,p2,p3] = ndgrid(1:3);
Result = [A(p3(:),1),A(p2(:),2),A(p1(:),3)];

MATLAB: Randn

You cannot do that. randn() is the random number generator for the normal distribution. The normal distribution must have infinite tails on both sides, so it is not possible to confine it to any particular range (not and keep it normally distributed.)

You could use a beta distribution to give specific limits, but not a normal distribution.
