Help with vectorizing where the indices of a matrix are found from another matrix

Hello,

I'm having trouble figuring out how to vectorize the following efficiently

EofGgivenXjU=zeros(numVars,maxDisc);
for ii=1:length(GofX)
    for jj=1:numVars
        EofGgivenXjU(jj,D(ii,jj))=EofGgivenXjU(jj,D(ii,jj))+newTermU(ii);
    end
end

Thank you very much

Brendan

In this case,

D =

     5 4
     5 3
     5 7
     3 1
     2 2
     2 2
     1 7
     3 5
     2 7
     5 7
     4 6
     2 4
     2 6
     4 1
     2 2
     4 6
     5 1
     2 4
     2 3
     1 6
     3 5
     3 1
     2 7
     5 3
     4 4
     5 7
     1 7
     3 2
     2 5
     5 5
     3 7
