I'd like to overlay a DEM on a (grayscale) hillshade, as is commonly done in ArcGIS. I've been trying to do this by plotting both and setting the transparency of the DEM (AlphaData) equal to the hillshade values (which range from 0 to 1). Not working. Any ideas?

Please check what your figure's 'renderer' property is set to. Transparency only works for OpenGL.

Hi Ajay,
you might want to check TopoToolbox, which includes such a function.

Another option is to use the shadem function.
