In lieu of irrelevant AI-generated link spam, consider the example:
% fake xyz data
n = 100;
x = linspace(0,100,n); % x is 100 units wide
y = linspace(0,250,n); % y is 250 units wide
[X Y] = meshgrid(x,y);
Z = zeros(size(X));
Z(25:50,25:50) = 2;
Z(75:90,75:90) = 4; % tallest z feature is only 4 units
% plot it
hs = surf(X,Y,Z);
hs.EdgeAlpha = 0.5;
% set the aspect ratio
% z-features are scaled 10x WRT x or y
% but x and y are 1:1 WRT each other
zsc = 10;
set(gca,'dataaspectratio',[zsc zsc 1])
