EUDMODEL(DVH), where DVH is a 2 column matrix corresponding to the cumulative, not differential, dose volume histogram. The 1st column corresponds to increasing absolute dose or percentage dose values, and the 2nd column to the corresponding absolute or relative volume value. The matrix must have a minimum of two rows, and both columns must be of equal length.
