/**
* 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
