Name

sech — Compute the element-wise hyperbolic secant of the argument.

Calling Sequence

y = sech(x)

Parameters

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].

Examples

    x=linspace(-10,10,1000)
    plot(x,sech(x))
