Operation of 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.

2(x+y) {{1,2}{3,4}} (-1) (returns {{-1,-2}{-3,-4}}) {{1}{1}}{{2}{3}} (returns {{6}}).
