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

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