Function sech

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

For matrices, the function is evaluated element wise.

Syntax

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

Examples

// sech(x) = 1/ cosh(x)
sech(0.5);       // returns 0.886818883970074
1 / cosh(0.5);   // returns 0.886818883970074
