surfacem: How to display nans in white color?

Hi there,

under the following link, http://www.mathworks.com/matlabcentral/newsreader/view_thread/140607 it was suggested by Sergey to use

h=imagesc(X,Y,C) set(h,'alphadata',~isnan(C))

to make the nans appear in white color. This works perfectly fine for imagesc but I have to use surfacem and in this case, the nans don't display in white, unfortunately. Does anybody know how to solve this problem?

Thanks in advance, Iris

I found it out myself. The solution is

h = surfacem(C) set(h,'alphadatamapping', 'none','alphadata', double(~isnan(C)), 'FaceAlpha', 'texturemap')
