Library of uniform distribution functions
This package provides
of the uniform distribution. Examples:
For more details of this distribution see Wikipedia.
Extends from Modelica.Icons.Package (Icon for standard packages).

Density of uniform distribution
Uniform.density(u, u_min=0, u_max=1);
This function computes the probability density function according to a uniform distribution in a band. Plot of the function:
For more details, see Wikipedia.
density(0.5) // = 1 density(0,-1,1) // = 0.5

Cumulative distribution function of uniform distribution
Uniform.cumulative(u, u_min=0, u_max=1);
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
Uniform.quantile(u, y_min=0, y_max=1);
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
