cscd — Computes the element-wise cosecant of the argument given in degree.
x = cscd(x)
The entries of y
are the cosecant
1/sin
of the entries of x
given in degree. The results are real and in ]-%inf -1]
U [1 %inf[
. or entries equal to
n*180
with n
integer, the
result is infinite (or an error depending on ieee mode). For entries equal to
n*90
with n
integer and
odd the result is exactly 1 or -1.
