# acosd

Returns the inverse cosine (in degrees) for each element of
`x`.

## Syntax

R = acosd(x)

## Inputs

`x`- Any valid scalar | vector | matrix

## Outputs

- R
- scalar | vector | matrix in degrees.

## Examples

Simple scalar
example:

`acosd(45)`

`R = 257.813i`

Simple vector
example:

`acosd([24,45])`

`R = [ 221.779i, 257.813i]`
