# removesigroi

Remove signal regions of interest

Since R2020b

## Syntax

``roilimsout = removesigroi(roilims,s)``

## Description

example

````roilimsout = removesigroi(roilims,s)` removes signal regions of interest specified in `roilims` that have a length of `s` samples or less.```

## Examples

collapse all

Create a two-column matrix of integers that can represent regions of interest of a signal. Remove any regions that are six samples in length or shorter.

```rois = [1 6; 17 26; 24 32; 36 40]; xrois = removesigroi(rois,6)```
```xrois = 2×2 17 26 24 32 ```

## Input Arguments

collapse all

Region-of-interest limits, specified as a two-column matrix of positive integers. The ith row of `roilims` contains nondecreasing indices corresponding to the beginning and end samples of the ith region of interest of a signal.

Example: `[5 8; 12 20; 18 25]` specifies a two-column region-of-interest matrix with three regions.

Data Types: `single` | `double` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint32` | `uint64`

Maximum length of regions of interest to remove, specified as a nonnegative integer.

Data Types: `single` | `double` | `int8` | `int16` | `int32` | `int64` | `uint8` | `uint16` | `uint32` | `uint64`

## Output Arguments

collapse all

Modified region-of-interest limits, returned as a two-column matrix of positive integers. Output limits are returned in sorted order using the `sortrows` function.
