  /**
   * Test whether two values are unequal.
   *
   * The function tests whether the relative difference between x and y is
   * larger than the configured epsilon. The function cannot be used to compare
   * values smaller than approximately 2.22e-16.
   *
   * For matrices, the function is evaluated element wise.
   * In case of complex numbers, x.re must unequal y.re, or x.im must unequal y.im.
   * Strings are compared by their numerical value.
   *
   * Values `null` and `undefined` are compared strictly, thus `null` is unequal
   * with everything except `null`, and `undefined` is unequal with everything
   * except `undefined`.
   *
   * Syntax:
   *
   *    math.unequal(x, y)
   *
   * Examples:
   *
   *    math.unequal(2 + 2, 3)       // returns true
   *    math.unequal(2 + 2, 4)       // returns false
   *
   *    const a = math.unit('50 cm')
   *    const b = math.unit('5 m')
   *    math.unequal(a, b)           // returns false
   *
   *    const c = [2, 5, 1]
   *    const d = [2, 7, 1]
   *
   *    math.unequal(c, d)           // returns [false, true, false]
   *    math.deepEqual(c, d)         // returns false
   *
   *    math.unequal(0, null)        // returns true
   * See also:
   *
   *    equal, deepEqual, smaller, smallerEq, larger, largerEq, compare
   *
   * @param  {number | BigNumber | Fraction | boolean | Complex | Unit | string | Array | Matrix | undefined} x First value to compare
   * @param  {number | BigNumber | Fraction | boolean | Complex | Unit | string | Array | Matrix | undefined} y Second value to compare
   * @return {boolean | Array | Matrix} Returns true when the compared values are unequal, else returns false
