[Trilinos-Users] Multidimensional Arrays

I have a question on multidimensional arrays with Epetra_Maps and
For example, suppose I have a set of n points. Associated with each
point I have coordinates (x,y,z) and a global Id that I use to create an
Epetra_Map. For a given point local index j, I can look up the
coordinates vec[3*j+k], k=0,1,2.
I would like to create an Epetra_Map that understands this and stores
the data so that I don't have to create 3 Epetra_Vectors (for X, Y, Z).
Is this possible? If not, what is the recommended best practice?
I see that there is Epetra_MultiVector with the following constructor,
but that doesn't appear to do what I want (unless I do a copy of all
incoming data into an array double *A that is not interlaced and then
use the constructor below to copy one more time)
Epetra_MultiVector(Epetra_DataAccess CV, const Epetra_BlockMap& Map,
double *A, int MyLDA, int NumVectors);
