Sets or returns the (i,j)th value (Double) of the 3x3 matrix, where i are
rows and j are columns.
| m[0,0] m[0,1] m[0,2] |
| m[1,0] m[1,1] m[1,2] |
| m[2,0] m[2,1] m[2,2] |
Tip: Value is the SIMatrix3 object's default property, which means
that you can call the method by just using the parenthesis and
leaving out the property name for example m(i,j).
