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 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.

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

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.
