@isuruf In #912 ,I think still MatrixSymbol needs to be implemented still,so could you please guide me here.
I have got this : Implementation of matrixsymbol in sympy.matrices.matrixexpr.py and would be added in matrices.h in symengine

@bhavishyagopesh, sympy is revisiting how they are implemented, so I think we should wait a little bit more to see how that pans out
@prateeksingh0001,
  1. Integers, Rationals, reals, complex are all implemented.
  2. I'm not sure I understand
  3. It's a design pattern and you can find great resources on the internet, see https://en.wikipedia.org/wiki/Visitor_pattern and http://eli.thegreenplace.net/2011/05/17/the-curiously-recurring-template-pattern-in-c
  4. yes
  5. Expression is separate. It's there to work easily with symengine objects without using RCPs
  6. types = SymEngine types. Because if there are n combinations for A and B each then visit(A, B) has nxn possibilities

@isuruf Do SymEngine at present provides functionality of dot and cross products?
