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)
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
