Calculate the hyperbolic secant of a value, defined as sech(x) = 1 / cosh(x).

For matrices, the function is evaluated element wise.

Syntax #

math.sech(x)

Parameters #

Parameter Type Description
x number | Complex | Unit | Array | Matrix Function input

Returns #

Type Description
number | Complex | Array | Matrix Hyperbolic secant of x
