unidrnd (Statistics Toolbox)

Random numbers from the discrete uniform distribution.

Syntax

R = unidrnd(N)
R = unidrnd(N,mm)
R = unidrnd(N,mm,nn)

Description

The discrete uniform distribution arises from experiments equivalent to drawing a number from one to N out of a hat.

R = unidrnd(N) generates discrete uniform random numbers with maximum N. The parameters in N must be positive integers. The size of R is the size of N.

R = unidrnd(N,mm) generates discrete uniform random numbers with maximum N, where mm is a 1-by-2 vector that contains the row and column dimensions of R.

R = unidrnd(N,mm,nn) generates discrete uniform random numbers with maximum N, where scalars mm and nn are the row and column dimensions of R.

Examples

In the Massachusetts lottery, a player chooses a four digit number. Generate random numbers for Monday through Saturday.

numbers = unidrnd(10000,1,6) - 1
numbers =
