surflm
in [Matlab]

From: Jamie on 19 Jul 2010 19:33 Hello! So, I've just discovered the surflm function. I'd been trying to write my own shadowing program for a while with naught but errors. So I got the surflm function to work just fine, in that it shows me a surface plot of the shadows created by the topography. My question is, however silly, I don't really understand how to get to the matrix it created to make the plot. In other words, surflm gives me access to the plot of shadows, but how to I get access to the actual data? What I need from surflm (or something else) is an actual matrix the same size of the map with zeros where there is no shadow, and ones where there is a shadow (or some other value system for indicating shadowed pixels). Does that make sense? My code is very simple: surf(DEM1) axesm shading flat surflm([latmin latmax], [lonmin lonmax], DEM1,[solar_az solar_elev]) Thank you for any help!
