Please post the code directly on not a link to a strange download portal. I did not understand, what your code does so far. Does it draw tge picture in the middle? What is the pictuire of the right side?

Part of this appears to be an aspect ratio (or zlim) matter.

However, notice that the one on the left has positive values on Z, whereas the one on the right has negative values on Z. This makes a difference in the colormap use.

I want the Z axis to look like a curve on the left picture. How to make it. Thank

If you want to get rid of the minus do:

zlim([-40 0]) % change limits, following walters remark

% now we take care about the minus
zticklabels(num2cell(-zticks)); % This creates new z-labels

Note if you update the zlims, you need to update the labels as well, because labels are just stickers that we put onto the z axis and they do not change when the axis changes.

This should help you get started. I just added some lines to your code to make it look more like the old one

hdl = surf(B);
shading interp
xlabel('row')
ylabel('column')
% added stuff
colormap(jet) % old colormap
colormap(flipud(colormap)) % invert colormap (following Walters Remark)
hdl.EdgeColor = 'k' % black lines

thank you sir. But I want the Z axis to look like a curve on the left picture. How to make it. _________ thank sir.

zlim([0 40]) or possibly zlim([-40 0])

thank you for x y z lim
