how to make smoother surf plot

if n == 1

Hz_snapshots(:,:,snap_count) = Hz; %save the current Hz

Ex_snapshots(:,:,snap_count) = Ex; %save the current Ex

Ey_snapshots(:,:,snap_count) = Ey; %save the current Ey

time_stamp(snap_count) = n; %save the time of the snapshot

snap_count = snap_count + 1; %increase the index for the next snapshot

elseif mod(n,round(nt/(ns-1))) == 0

Hz_snapshots(:,:,snap_count) = Hz; %save the current Hz

Ex_snapshots(:,:,snap_count) = Ex; %save the current Ex

Ey_snapshots(:,:,snap_count) = Ey; %save the current Ey

time_stamp(snap_count) = n; %save the time of the snapshot

snap_count = snap_count + 1; %increase the index for the next snapshot

end

xx = 0:dx:a;

yy = 0:dy:b;

[Y, X] = meshgrid(yy,xx);

surf(X,Y,Hz,'LineStyle','none', 'FaceColor', 'interp')

axis([0 a 0 b -1 1])

title(strcat('Hz Field at Time n = ',num2str(n)))

xlabel('x (m)')

ylabel('y (m)')

zlabel('Hz (V/m)')

Hello guys. I made a plot by using those statements. Hz is 101x81 matrix having the form of a checkerboard.

Ex, Hz= (2680, 0, 2680, 0, 2680;

0, 6308, 0, 6308, 0;

9359, 0, 9359, 0, 9359)

And I want to remove those 'spike shape' from my plot and change it to a smooth plot. How can I do this?

Or, if there is any method to remove '0' values from the Hz matrix and push the other values ​​to the left, and plot it, please let me know.

Thanks!!

Have you tried to smooth your data with smooth function?

[Junseob Kim]

No. I didn't know about that function. Do you think that would be working?

[Luna]

Yes, you can use several smoothing algorithms. By default it uses moving average.
