sech

Compute the element-wise hyperbolic secant of the argument.

Calling Sequence

y = sech(x)

Arguments

:x Real or complex array. : :y Real or complex array. :

Description

Compute the element-wise hyperbolic secant of the argument. The hyperbolic secant is defined as 1/cosh. For real data the results are real and in [0 1].
