Low quality when exporting graph in emf

Hello,

The problem that happens to me is divided into two parts.

1. It happens that when I export a graphic in emf vector format, when I open it in Word, it loses all the quality and it no longer looks like a graphic in vector format. Rather it looks like a graphic in raster format and very low quality. Even when I save it to pdf it continues with this problem, see figure 1 in the pdf file. To better illustrate my situation, by way of an example I show my problem through this simple code. In addition, I attach the pdf file where this problem is evident. I have noticed that the problem manifests itself as the number of points in the grid increases (when the delta variable is decreased). So, what can I do?, without decreasing the number of points in the mesh to avoid losing the "smoothness" of the surface.

2. If I use a smaller number of points in the grid, the vectorial quality is maintained, but the surface lines are appreciated once exported in emf and save it to pdf. See in the figure 2 in the pdf file several white thin lines in the surface. So, what can I do?

delta = 0.2;
[X,Y] = meshgrid(-2:delta:2);
Z = X.*exp(-X.^2 - Y.^2);

surf(X,Y,Z,'EdgeColor','interp','FaceColor','interp')

It worked for me.
