Uniform Distribution (Discrete)

The discrete uniform pdf is

$y = f (x | N) = \frac{1}{N} I_{(1, ..., N)} (x)$

The discrete uniform distribution is a simple distribution that puts equal weight on the integers from one toN.

As for all discrete distributions, the cdf is a step function. The plot shows the discrete uniform cdf forN= 10.

x = 0:10; y = unidcdf(x,10); figure; stairs(x,y) h = gca; h.XLim = [0 11];

Figure contains an axes object. The axes object contains an object of type stair.
