Let me see if I understand you... Does the matrix of indices contain
positive integers? I think what you are saying is that for some
entry in matrix A, say A(1,2,3) = 43.2 the corresponding entry in B,
B(1,2,3) would contain something like (4,7) which you would want to
put into matrix C such that C(4,7) = 43.2
Is that correct?
