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.

Answer 1

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 = -.')
