Given a multidimensional array A = MxMxMx...xM, where ndims(A)=n and the subscript array b=[a1, a2, ..., an]. How to get A(a1, a2, a3, ..., an)? I've tried A(b). It's not a correct way. And a correct way is to write a function to convert the subscript array to the index, saying i, and then we can use A(i) to get what I want. Is there an easier way?
Thanks

lin_ind=sub2ind(size(A),a1,a2,a3)
