  /**
   * Subtract two values, `x - y`.
   * For matrices, the function is evaluated element wise.
   *
   * Syntax:
   *
   *    math.subtract(x, y)
   *
   * Examples:
   *
   *    math.subtract(5.3, 2)        // returns number 3.3
   *
   *    const a = math.complex(2, 3)
   *    const b = math.complex(4, 1)
   *    math.subtract(a, b)          // returns Complex -2 + 2i
   *
   *    math.subtract([5, 7, 4], 4)  // returns Array [1, 3, 0]
   *
   *    const c = math.unit('2.1 km')
   *    const d = math.unit('500m')
   *    math.subtract(c, d)          // returns Unit 1.6 km
   *
   * See also:
   *
   *    add
   *
   * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} x
   *            Initial value
   * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} y
   *            Value to subtract from `x`
   * @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}
   *            Subtraction of `x` and `y`
