* Operation
  Operation of multiplication.
Syntax  x*y, or , x y(implied multiplication).
Notes Multiplication accepts either:
  • Two numbers
  • Matrix followed by a number (term wise multiplication of the matrix).
    Note: number * matrix will return an error.
  • Two matrices, whose dimensions are compatible, i.e the number of columns in the first argument is the same as the number of rows in the 2-nd.
Examples
2(x+y)

{{1,2}{3,4}} (-1)
(returns {{-1,-2}{-3,-4}})

{{1}{1}}{{2}{3}}
(returns {{6}}).
