ASECD Inverse Secant Degrees Function

Section: Mathematical Functions

Usage

Computes the inverse secant of the argument, but returns the argument in degrees instead of radians (as is the case for asec. The syntax for its use is 
   y = asecd(x)

Examples

The inverse secant of 2/sqrt(2) should be 45 degrees: 
--> asecd(2/sqrt(2))

ans = 
  45.0000 +  0.0000i

and the inverse secant of 2 should be 60 degrees: 

--> asecd(2)

ans = 
  60.0000 +  0.0000i
