Hey all, I want to know when we using griddedinterpolant while we have some NaN in our data set, are they NaNs fills by griddedinterpolant? Or they remain as NaN?
MATLAB: Is griddedinterpolant omits NaN

One option is to set x, y, and z values to NaN if they do not fall in the appropriate region:
[x1, z1] = meshgrid(linspace(0,1,500));y1 = sqrt(x1);[x2, y2] = meshgrid(linspace(0,1,500));z2 = 1 - y2;i1 = y1+z1>1;i2 = y2<sqrt(x2);x1(i1) = NaN;y1(i1) = NaN;z1(i1) = NaN;surf(x1,y1,z1,'FaceColor','b','FaceAlpha',0.5,'EdgeColor','none');hold on;x2(i2) = NaN;y2(i2) = NaN;z2(i2) = NaN;surf(x2,y2,z2,'FaceColor','b','FaceAlpha',0.3,'EdgeColor','none');view([120 30])zlim([0 1.5]);ylim([0 1.5]);xlim([0 1.5]);xlabel('x','FontSize',20);ylabel('y','FontSize',20);zlabel('z','FontSize',20);
This behavior was fixed in R2012a. If you are current on SMS, you can download R2012a or R2012b for free.
