how to generate uniform discrete distribution starts from zero?

Hi;

I want to generate a matrix that generated from uniform discrete distribution. I use unidrnd command but this command starts number from 1. For example I write:

A=unidrnd(2,5,5) and result is:

A=

1 1 1 1 1

1 2 2 1 1

2 2 1 2 1

1 2 2 2 1

1 1 1 2 2

But I need that random numbers generated from uniform discrete distribution should start from zero not 1.

Any suggestion about the problem?

Thanks in advance; Regards...

To have a lower value of 0 and still keep your top value of 2, you need to pass in one more than that as the first argument to unidrnd(), and then subtract 1

>> A=unidrnd(3,5,5)-1
A =
     2     2     2     1     1
     2     0     2     1     1
     1     0     0     2     1
     1     0     2     2     2
     0     0     0     0     2

You can also use randi() and specify the starting and stopping value:

A = randi([0, 2], 5, 5)
