(< < C|D >, < E|F > >^6 . < 0,1 >)[1];

Be careful with your use of `^`. I can tell that by A^j you mean A_j (i.e. A-subscript-j), because if you really meant exponentiation (the usual meaning of `^`), then your question is nonsensical.

I noted the entries in lowercase instead of uppercase. Due to the associative law it can be counted easily:

A:=Matrix([[a, b], [c, d]]):
B:=Matrix([[0], [1]]):
(A^6).B;

thanks guys you have been very helpfuk, if

thanks guys you have been very helpfuk, if all the terms have values e.g any number, is there a way to get maple to plot say A_1 to A_6 if that makes sense. e.g if A_1=3, A_2=4, A_3 = 5 etc then plot A_j against these numbers?

Doesn't make sense to me

I managed to figure out what your original post meant, but I can't make sense of this. How about trying to do what you want in a worksheet and uploading the results?
