A quick check seems to say no.

There is no obvious way to access the elements of an Elemental matrix
except to directly access the elemental data structure (which presumably is
hairy) or to MatConvert(A,MATDENSE,MAT_INITIAL_MATRIX,&Adense); and then access
in the dense format (note this conversion is expensive and needs to do
communication).
Why do you wish to access the values directly instead of use them
indirectly with the API, such as matrix-vector products, factorizations etc?
