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

Written and tested in MATLAB Student Version (Version 7.0.0.27) Release 14, and should work in other releases.
