MATLAB: Contour plot decimal places label

Question

Hello,

I am trying to plot a contour so that in each countour line a value (label) appears. At the moment the number of decimal places appearing in the label is 4, is there any way to force matlab to present only one decimal place, having for example 32.0, 40.4, etc. ?

Below is the code I am presently using. Thanks in advance for any help.

figure(f1)
subplot(3,1,1);
[cs,h]=contourf(xgrid,ygrid,U,10); hold on;
clabel(cs,h);
set(gca, 'CLim', [12 50]);
xlabel('$y$ $(cm)$','interpreter','latex','Fontsize',18,'Fontname','Times'), 
ylabel('$z$ $(cm)$','interpreter','latex','Fontsize',18,'Fontname','Times'), 
axis([83 92 1.2 3.9]); 
colormap('jet') 
colorbar

Answer 1

[cs,h] = contourf(sort(rand(50,50)*10), 20);
clabel(cs,h);
h.LevelList = round(h.LevelList, 1);
