secd
computes the element-wise secant of the argument given in degree
Syntax
y = secd(x)
Arguments
- x
a real array.
- y
a real array.
Description
The entries of y are the secant
1/cos(x) of the entries of x given in
degree. The results are real and in ]-∞, -1] ∪ [1, ∞[.
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).
