Return column index (easy question)

I am trying to return a maximum eigenvalue and its associated
eigenvector, but can't because I don't know how to find the column
number associated with the maximum eigenvalue. For example,

[v d]=eig([1 2 3; 4 5 6; 7 8 9]);

max_eig_val=max(max(d));
max_eig_vec=v(:,??);

What can I put in for ??. ColumnIndex(max(max(d))) would be great if
it existed.

Any ideas??

Thanks so much,

Tim
