asecd

Inverse secant in degrees

Syntax

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

collapse all

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.

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.
