HI all!
I have a data with Lat*Lon*Levels (i.e. 161*161*18 double) and I want to plot a filled 3-D contour to show variation throughout the levels.
I am getting error for dimensions as dimension should be 2*2.
Can someone help?

You can plot one level at a time:
for i = 1:18
plot(lon,lat,levels(:,:,i)')
shading interp
drawnow
end
If you want to show variation, you need to decide the plane to display and then plot it. For this you need to use slice. Read about slice.

Ran in:
It would help to know the data and the desired result.
One option is to use the surf function and contour3 —
[X,Y,Z] = peaks(50);
figure
surf(X, Y, Z+5, 'EdgeColor','none')
hold on
contour3(X, Y, Z+5, 15, '-k', 'LineWidth',1)
hold off
grid on
xlabel('Latitude (°)')
ylabel('Longitude (°)')
zlabel('Elevation (km)')
There are probably Mapping Toolbox functions that work similarly if that is being used in the data analysis.
