Math.js is an extensive math library for JavaScript and Node.js. It features a flexible expression parser and offers an integrated solution to work with numbers, big numbers, complex numbers, units, and matrices.

# Function xor

Logical `xor`. Test whether one and only one value is defined with a nonzero/nonempty value.
For matrices, the function is evaluated element wise.


## Syntax

```js
math.xor(x, y)
```

### Parameters

Parameter | Type | Description
--------- | ---- | -----------
`x` | Number | BigNumber | Boolean | Complex | Unit | Array | Matrix | null | First value to check
`y` | Number | BigNumber | Boolean | Complex | Unit | Array | Matrix | null | Second value to check

### Returns

Type | Description
---- | -----------
Boolean | Array | Matrix |  Returns true when one and only one input is defined with a nonzero/nonempty value.


## Examples

```js
math.xor(2, 4);   // returns false

a = [2, 0, 0];
b = [2, 7, 0];
c = 0;

math.xor(a, b);   // returns [false, true, false]
math.xor(a, c);   // returns [true, false, false]
```
