# asecd

Inverse secant in degrees

## Description

example

Y = asecd(X) returns the inverse secant (sec-1) of the elements of X in degrees. The function's domain and range include complex values. For real elements of X in the domain [-Inf,1] and [1,Inf], asecd returns values in the range [0, 180]. For values of X outside this range, asecd returns complex values.

## Examples

### Inverse Secant of Vector

```x = [10 1 Inf];
y = asecd(x)
```
```y =

84.2608         0   90.0000```

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

### Inverse Secant of Complex Value

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

64.0864 +30.4033i```

## Input Arguments

### X — Secant of anglescalar value | vector | matrix | N-D array

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

### Y — Angle in degreesscalar value | vector | matrix | N-D array

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