After generating the poligons vertices and defined their faces, I've plotted the polygons with the patch function:

pp = patch('Faces',faces,'Vertices',vertices);

and then I've defined the patches colors:

set(pp,'FaceColor','flat',...
       'FaceVertexCData',cdata,...
       'CDataMapping','direct',...
       'EdgeAlpha',.4,'EdgeColor','b')

Getting the following Matlab plot:

Now, I would like to visualize these polygons with Google Earth, but I don't know how.

I've tried the function kmlwrite, but I could pass to it only the polygons' vertices's coordinates, generating a kml file with all points and no polygon, as shown below:

The question is: wow can I write geospatial polygons (and their colors) into a .kml file with kmlwrite function?

Thanks

I've found the solution of my problem in the KML ToolBox:

in particular in the k.poly3 function.
