in this case it is easier to convert the matlab plot
into a PostScript vector file and read the coordinates
or alternatively to an eps Image which can then be
overwrite by other drawings.

pst-IIID is really experimental, but can plot 3d functions.
The psPlot can be adapted to a fileplot, but this is
not really easy.

However, I am on vacation in France until mid of august.
