surf plot of f(x,y). With gridlines, but more sparse than default

Question

surf(x,y,z) where z is oscillatory. Therefore x,y are 100x100. I want the gridlines (don't want to use flat or interp options). However, too many gridlines don't look good. Looking for a way to reduce gridlines by 50% or 75% etc. in both x and y coord.

You might want to consider changing the edge transparency. For instance, surf(x,y,z,'EdgeAlpha',0.5). You could also change the grid color to gray instead of black. You could also change the edge style. — Ben Grossmann, Dec 14 '21 at 00:00
You could also change the edge width. Unfortunately, it doesn't look like matlab provides an easy way to manually set the gridline spacing. If you really want to, I suspect that you could do so by using the AlphaData parameter. — Ben Grossmann, Dec 14 '21 at 00:07
By the way, this strikes me as a question that's more appropriate for Stack Overflow. — Ben Grossmann, Dec 14 '21 at 00:08

To supplement the comments, here's a quick demonstration of what's going on.

Code:

f = @(x,y) exp(-x.^2 - y.^2);
L = 2;
dx = .01;
dy = dx;
x = -L:dx:L;
y = x;
[X,Y] = meshgrid(x,y);
Z = f(X,Y);
tiledlayout(2,2);
nexttile
surf(X,Y,Z);
title('Default')
nexttile
surf(X,Y,Z,'EdgeAlpha',0.2)
title('EdgeAlpha = 0.2')
nexttile
surf(X,Y,Z,'LineStyle',':')
title('Line Style = :')
nexttile
surf(X,Y,Z,'LineStyle','-.')
title('Line Style = -.')
