# asecd

Inverse secant in degrees

## Syntax

``Y = asecd(X)``

## Description

example

````Y = asecd(X)` returns the inverse secant (sec-1) of the elements of `X` in degrees. The function accepts both real and complex inputs. For real values of `X` in the intervals [-∞, -1] and [1, ∞], `asecd(X)` returns values in the interval [0, 180].For real values of `X` in the interval (-1, 1) and for complex values of `X`, `asecd(X)` returns complex values. ```

## Examples

collapse all

```x = [10 1 Inf]; y = asecd(x)```
```y = 1×3 84.2608 0 90.0000 ```

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

`asecd(1+i)`
```ans = 64.0864 + 30.4033i ```

## Input Arguments

collapse all

Secant of angle, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The `asecd` 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`.
