   * Multiply two matrices element wise. The function accepts both matrices and
   * scalar values.
   *
   * Syntax:
   *
   *    math.dotMultiply(x, y)
   *
   * Examples:
   *
   *    math.dotMultiply(2, 4); // returns 8
   *
   *    a = [[9, 5], [6, 1]];
   *    b = [[3, 2], [5, 2]];
   *
   *    math.dotMultiply(a, b); // returns [[27, 10], [30, 2]]
   *    math.multiply(a, b);    // returns [[52, 28], [23, 14]]
   *

   *
   * @param  {Number | BigNumber | Boolean | Complex | Unit | Array | Matrix | null} x Left hand value
   * @param  {Number | BigNumber | Boolean | Complex | Unit | Array | Matrix | null} y Right hand value
   * @return {Number | BigNumber | Complex | Unit | Array | Matrix}                    Multiplication of `x` and `y`
