* Calculate the hyperbolic secant of a value,

*
* For matrices, the function is evaluated element wise.
*
* Syntax:
*
* math.sech(x)
*
* Examples:
*
* // sech(x) = 1/ cosh(x)
* math.sech(0.5) // returns 0.886818883970074
* 1 / math.cosh(0.5) // returns 0.886818883970074
*
* See also:
*
* cosh, csch, coth
*
* @param {number | Complex | Unit | Array | Matrix} x Function input
* @return {number | Complex | Array | Matrix} Hyperbolic secant of x
