Cumulative distribution function of uniform distribution

Information

Syntax

Uniform.cumulative(u, u_min=0, u_max=1);

Description

This function computes the cumulative distribution function according to a uniform distribution in a band. The returned value y is in the range:

Quantile of uniform distribution

Information

Syntax

Uniform.quantile(u, y_min=0, y_max=1);

Description

This function computes the inverse cumulative distribution function (= quantile) according to a uniform distribution in a band. Input argument u must be in the range:

0 ≤ u ≤ 1

The returned number y is in the range:

y_min ≤ y ≤ y_max

Extends from Modelica.Math.Distributions.Interfaces.partialQuantile (Common interface of quantile functions (= inverse cumulative distribution functions)).

Inputs

NameDescription
uRandom number in the range 0 <= u <= 1
y_minLower limit of y
y_maxUpper limit of y

Outputs

NameDescription
