# acotd

Inverse cotangent in degrees

## Syntax

• ``Y = acotd(X)``
example

## Description

example

````Y = acotd(X)` returns the inverse cotangent (cot-1) of the elements of `X` in degrees. The function's domain and range include complex values. For real elements of `X` in the range [-Inf,Inf], `acotd` returns values in the range [-90,90]. For complex values of `X`, `acotd` returns complex values.```

## Examples

collapse all

```x = [0 20 Inf]; y = acotd(x) ```
```y = 90.0000 2.8624 0 ```

The `acotd` operation is element-wise when you pass a vector, matrix, or N-D array.

```acotd(1+i) ```
```ans = 31.7175 -23.0535i ```

## Input Arguments

collapse all

Cotangent of angle, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The `acotd` operation is element-wise when `X` is non-scalar.

Data Types: `single` | `double`
Complex Number Support: Yes

## Output Arguments

collapse all

Angle in degrees, returned as a real-valued or complex-valued scalar, vector, matrix, or N-D array of the same size as `X`.
