     23    * Calculate the inverse secant of a value. Defined as `asec(x) = acos(1/x)`.
     24    *
     25    * For matrices, the function is evaluated element wise.
     26    *
     27    * Syntax:
     28    *
     29    *    math.asec(x)
     30    *
     31    * Examples:
     32    *
     33    *    math.asec(0.5)           // returns 1.0471975511965979
     34    *    math.asec(math.sec(1.5)) // returns 1.5
     35    *
     36    *    math.asec(2)             // returns 0 + 1.3169578969248166 i
     37    *
     38    * See also:
     39    *
     40    *    acos, acot, acsc
     41    *
     42    * @param {number | Complex | Array | Matrix} x  Function input
     43    * @return {number | Complex | Array | Matrix} The arc secant of x
