     13    * Calculate the hyperbolic arccosecant of a value,
     14    * defined as `acsch(x) = asinh(1/x) = ln(1/x + sqrt(1/x^2 + 1))`.
     15    *
     16    * For matrices, the function is evaluated element wise.
     17    *
     18    * Syntax:
     19    *
     20    *    math.acsch(x)
     21    *
     22    * Examples:
     23    *
     24    *    math.acsch(0.5)       // returns 1.4436354751788103
