     20    * Logical `not`. Flips boolean value of a given parameter.
     21    * For matrices, the function is evaluated element wise.
     22    *
     23    * Syntax:
     24    *
     25    *    math.not(x)
     26    *
     27    * Examples:
     28    *
     29    *    math.not(2)      // returns false
     30    *    math.not(0)      // returns true
     31    *    math.not(true)   // returns false
     32    *
     33    *    a = [2, -7, 0]
     34    *    math.not(a)      // returns [false, false, true]
     35    *
     36    * See also:
     37    *
     38    *    and, or, xor
     39    *
     40    * @param  {number | BigNumber | Complex | Unit | Array | Matrix} x First value to check
     41    * @return {boolean | Array | Matrix}
     42    *            Returns true when input is a zero or empty value.
