# prob.UniformDistribution class

Package: prob
Superclasses: prob.ParametricTruncatableDistribution

Uniform probability distribution object

## Description

`prob.UniformDistribution` is an object consisting of parameters and a model description for a uniform probability distribution. Create a probability distribution object with specified parameters using `makedist`.

## Construction

`pd = makedist('Uniform')` creates a uniform probability distribution object using the default parameter values.

`pd = makedist('Uniform','Lower',lower,'Upper',upper)` creates a uniform distribution object using the specified parameter values.

### Input Arguments

expand all

Lower limit for the uniform distribution, specified as a scalar value.

Data Types: `single` | `double`

Upper parameter for the uniform distribution, specified as a scalar value greater than `lower`.

Data Types: `single` | `double`

## Properties

expand all

Lower parameter for the uniform distribution, stored as a scalar value.

Data Types: `single` | `double`

Upper parameter for the uniform distribution, stored as a scalar value greater than `lower`.

Data Types: `single` | `double`

Probability distribution name, stored as a character vector. This property is read-only.

Data Types: `char`

Logical flag for truncated distribution, stored as a logical value. If `IsTruncated` equals `0`, the distribution is not truncated. If `IsTruncated` equals `1`, the distribution is truncated. This property is read-only.

Data Types: `logical`

Number of parameters for the probability distribution, stored as a positive integer value. This property is read-only.

Data Types: `single` | `double`

Distribution parameter descriptions, stored as a cell array of character vectors. Each cell contains a short description of one distribution parameter. This property is read-only.

Data Types: `char`

Distribution parameter names, stored as a cell array of character vectors. This property is read-only.

Data Types: `char`

Distribution parameter values, stored as a vector. This property is read-only.

Data Types: `single` | `double`

Truncation interval for the probability distribution, stored as a vector containing the lower and upper truncation boundaries. This property is read-only.

Data Types: `single` | `double`

## Examples

expand all

Create a uniform distribution object using the default parameter values.

```pd = makedist('Uniform') ```
```pd = UniformDistribution Uniform distribution Lower = 0 Upper = 1 ```

Create a uniform distribution object by specifying parameter values.

```pd = makedist('Uniform','Lower',-4,'Upper',2) ```
```pd = UniformDistribution Uniform distribution Lower = -4 Upper = 2 ```

Compute the interquartile range of the distribution

```r = iqr(pd) ```
```r = 3 ```
