unifpdf (Statistics Toolbox)

Continuous uniform probability density function (pdf).

Syntax

Y = unifpdf(X,A,B)

Description

unifpdf(X,A,B) computes the continuous uniform pdf with parameters A and B at the values in X. The arguments X, A, and B must all be the same size except that scalar arguments function as constant matrices of the common size of the other arguments.

The parameter B must be greater than A.

The continuous uniform distribution pdf is:

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

Examples

For fixed a and b, the uniform pdf is constant.

x = 0.1:0.1:0.6;
y = unifpdf(x)

y =

     1     1     1     1     1     1

What if x is not between a and b?

y = unifpdf(-1,0,1)

y =

     0
