      BB(d,1)=[vpa(B.X(d,1))]; % Error is Reference to non-existent field 'X'.

Reza - I think that some of your code is missing. Your code is assuming that B is a structure that has a field named X. This is not the case and so the above error message makes sense. Please update your question with the complete code (including how you define d3, d5, and d6) and explain why you are trying to access X from B.
