secd

Compute the element-wise secant of the argument given in degree.

Calling Sequence

y = secd(x)

Arguments

:x Real array. : :y Real array. :

Description

The entries of y are the secant 1/cos of the entries of x given in degree. The results are real and in ]-%inf -1] U [1 %inf[. For entries equal to n*180 with n integer, the result is exactly -1 or +1. For entries equal to n*90`with `n integer and odd the result is infinite (or an error depending on ieee mode).

Examples

secd(90)
`sec`_(%pi/2)
