     21    * Calculate the hyperbolic cosecant of a value,
     22    * defined as `csch(x) = 1 / sinh(x)`.
     23    *
     24    * For matrices, the function is evaluated element wise.
     25    *
     26    * Syntax:
     27    *
     28    *    math.csch(x)
     29    *
     30    * Examples:
     31    *
     32    *    // csch(x) = 1/ sinh(x)
     33    *    math.csch(0.5)       // returns 1.9190347513349437
     34    *    1 / math.sinh(0.5)   // returns 1.9190347513349437
     35    *
     36    * See also:
     37    *
     38    *    sinh, sech, coth
