secd
computes the element-wise secant of the argument given in degree
Calling Sequence
y = secd(x)
Arguments
- x
a real array.
- y
a real array.
Description
The entries of y are the secant
of the entries of x given in
degree. The results are real and in 
.
For entries equal to n*180 with
n integer, the result is exactly -1
or +1. For entries equal to n*90with
n integer and odd the result is infinite (or an error
depending on ieee mode).
Examples
secd(90) sec(%pi/2)
