     46    * Multiply two matrices element wise. The function accepts both matrices and
     47    * scalar values.
     48    *
     49    * Syntax:
     50    *
     51    *    math.dotMultiply(x, y)
     52    *
     53    * Examples:
     54    *
     55    *    math.dotMultiply(2, 4) // returns 8
     56    *
     57    *    a = [[9, 5], [6, 1]]
     58    *    b = [[3, 2], [5, 2]]
     59    *
     60    *    math.dotMultiply(a, b) // returns [[27, 10], [30, 2]]
     61    *    math.multiply(a, b)    // returns [[52, 28], [23, 14]]
     62    *

     68    * @param  {number | BigNumber | Fraction | Complex | Unit | Array | Matrix} y Right hand value
     69    * @return {number | BigNumber | Fraction | Complex | Unit | Array | Matrix}                    Multiplication of `x` and `y`
