  /**
   * Divide two matrices element wise. The function accepts both matrices and
   * scalar values.
   *
   * Syntax:
   *
   *    math.dotDivide(x, y)
   *
   * Examples:
   *
   *    math.dotDivide(2, 4)   // returns 0.5
   *
   *    a = [[9, 5], [6, 1]]
   *    b = [[3, 2], [5, 2]]
   *
   *    math.dotDivide(a, b)   // returns [[3, 2.5], [1.2, 0.5]]
   *    math.divide(a, b)      // returns [[1.75, 0.75], [-1.75, 2.25]]
   *
   * See also:
   *
   *    divide, multiply, dotMultiply
   *
   * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} x Numerator
   * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} y Denominator
   * @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}                    Quotient, `x ./ y`
