I am trying to generate a vector graphics file from a surface plot.
[X,Y] = meshgrid(-1.5:0.1:1.5,-1.5:0.1:1.5);
Z = (abs(X).*(abs(X) > abs(Y)) + abs(Y).*(abs(X) <= abs(Y))).*...
((abs(X) < 1) & (abs(Y) < 1)) + 1.*((abs(X)>=1) | (abs(Y)>=1)) + ...
max(2*X-2,0)-min(2*X+2,0)+max(2*Y-2,0)-min(2*Y+2,0);
fig=figure;
surf(X,Y,Z);
view(gca,[-65 10]);
This results is the plot that I want.
If I switch to Painters in order to save the figure as a vector graphics file, I get jagged edges:
fig.Renderer='Painters';
Any ideas how I can fix this?

What happens if you set "FaceColor" to "interp" (default is "flat") on the surf object? It fixes the jagge edge for me (2017a or b on mac)
[X,Y] = meshgrid(-1.5:0.1:1.5,-1.5:0.1:1.5);
Z = (abs(X).*(abs(X) > abs(Y)) + abs(Y).*(abs(X) <= abs(Y))).*...
((abs(X) < 1) & (abs(Y) < 1)) + 1.*((abs(X)>=1) | (abs(Y)>=1)) + ...
max(2*X-2,0)-min(2*X+2,0)+max(2*Y-2,0)-min(2*Y+2,0);
fig=figure;
s = surf(X,Y,Z);
view(gca,[-65 10]);
s.FaceColor = 'interp'
