Returns the inverse secant (in radians) for each element of the argument.

Syntax

R = asec(a)

Inputs

a
Dimension: scalar | vector | matrix

Outputs

R
The angle result (in radians).

Examples

Scalar input:
R = asec(2/sqrt(3))
R = 0.523598776
Matrix input:
R = asec([1, 2/sqrt(3); 2, sqrt(2)])
R = [Matrix] 2 x 2
