# iqr

Interquartile range of data set

## Description

returns the
interquartile range values of elements in input data `r`

= iqr(`A`

)`A`

.

If

`A`

is a vector, then`r`

is the difference between the 75th and the 25th percentiles of the data contained in`A`

.If

`A`

is a matrix, then`r`

is a row vector containing the difference between the 75th and the 25th percentiles of the sample data in each column of`A`

.If

`A`

is a multidimensional array, then`r`

contains the interquartile range values computed along the first array dimension whose size does not equal 1. The size of`r`

along this dimension is 1, while the sizes of all other dimensions remain the same as the input data.
