Inverse secant in degrees
Y = asecd(X)
returns
the inverse secant (sec-1) of the elements
of Y
= asecd(X
)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.
