lat= 10848x10848 double and lon= 10848x10848 double. How to make spatial map with this ?

I have two matrix lat and lon. But the problem is lat= 10848x10848 double and lon= 10848x10848 double. How to make spatial map with this ? also lat and lon matfile size are high. 459685kb each

If they are in a form as you'd get from meshgrid(), then you can easily make a spatial map using surf() among other functions. (I decreased the size to get the code to run in 55 seconds or less, i.e., to show up here - in your case you may have no problem doing this with the 10848 size matrices.)

[lat,lon] = meshgrid(linspace(-90,90,1084),linspace(-90,90,1084));
size(lat)

ans = 1×2

1084 1084

size(lon)

ans = 1×2

1084 1084

surf(lon,lat,8100-lat.^2-lon.^2,'EdgeColor','none');
view([0 90]);
