# wrapTo2Pi

Wrap angle in radians to [0 2*pi]

## Syntax

``lambdaWrapped = wrapTo2Pi(lambda)``

## Description

example

````lambdaWrapped = wrapTo2Pi(lambda)` wraps angles in `lambda`, in radians, to the interval ```[0, 2*pi]``` such that 0 maps to 0 and `2*pi` maps to `2*pi`. In general, positive multiples of `2*pi` map to `2*pi` and negative multiples of `2*pi` map to 0.```

## Examples

collapse all

Specify a short list of angles to wrap.

`lambda = [-2*pi -pi-0.1 -pi -2.8 3.1 pi pi+1 2*pi];`

Wrap the angles to the range [0, 2$\pi$] radians.

`lambdaWrapped = wrapTo2Pi(lambda)`
```lambdaWrapped = 1×8 0 3.0416 3.1416 3.4832 3.1000 3.1416 4.1416 6.2832 ```

Specify a second list of angles, and wrap them.

```lambda2 = -10:0.1:10; lambda2Wrapped = wrapTo2Pi(lambda2);```

Plot the wrapped angles. The wrapped angles stay in the range [0, 2$\pi$] radians.

```plot(lambda2,lambda2Wrapped) xlabel("Angle (radians)") ylabel("Wrapped Angle (radians)") grid on```

## Input Arguments
