I think it is still possible to get Ada 83 code from MatLab [if MathWorks 
did not cancelled this feature].

All this can be easily achived in Ada. Just derive all your types from the 
same tagged base and use smart pointers to the objects.

The reverse cannot be achived. I.e. with MatLab one cannot develop systems 
of same scale, maintainability, performance and safety as one could do in 
Ada.
