     12    * Calculate the hyperbolic cosine of a value,
     13    * defined as `cosh(x) = 1/2 * (exp(x) + exp(-x))`.
     14    *
     15    * For matrices, the function is evaluated element wise.
     16    *
     17    * Syntax:
     18    *
     19    *    math.cosh(x)
     20    *
     21    * Examples:
     22    *
     23    *    math.cosh(0.5)       // returns number 1.1276259652063807
     24    *
     25    * See also:
     26    *
     27    *    sinh, tanh
     28    *
     29    * @param {number | BigNumber | Complex | Unit | Array | Matrix} x  Function input
     30    * @return {number | BigNumber | Complex | Array | Matrix} Hyperbolic cosine of x
