unifcdf (Statistics Toolbox)

Continuous uniform cumulative distribution function (cdf).

Syntax

P = unifcdf(X,A,B)

Description

P = unifcdf(X,A,B) computes the uniform cdf at each of the values in X using the corresponding parameters in A and B (the minimum and maximum values, respectively). Vector or matrix inputs for X, A, and B must all have the same size. A scalar input is expanded to a constant matrix with the same dimensions as the other inputs.

The uniform cdf is

The standard uniform distribution has A = 0 and B = 1.

Examples

What is the probability that an observation from a standard uniform distribution will be less than 0.75?

probability = unifcdf(0.75)
probability =
    0.7500

What is the probability that an observation from a uniform distribution with a = -1 and b = 1 will be less than 0.75?

probability = unifcdf(0.75,-1,1)
probability =
    0.8750
