What function to plot lat, lon and a variable on a topographic map?

My variables are latitude, longitude and land surface temperature and are set up as 1200 x 1200 tables. I would like to plot the land surface temperature that correspond with the latitude and longitude values for the Northeastern U.S. area.

When I load topo and run my code:

plot(geoshow(lat, lon, final_lst_day))

I receive the error:

Error using plot
Not enough input arguments.

When I do not load topo, the plot will actually run but comes out blank because I did not load any topographic data to plot it on.

Is geoshow the appropriate function to run? I have tried meshgrid but also am getting an error.

Thank you for the help!

There's no need to call plot if you're using geoshow. Initialize a map with worldmap then plot the data with geoshow.

[goyanks1989]

do you have any other suggestions besides worldmap? I do not have the mapping tool installed with my version of Matlab.

Thank you!

If you don't have the Mapping Toolbox, you can't use geoshow either. But you can do

imagesc(lon,lat,final_lst_day) 
axis xy image 
hold on 
borders('countries')

if you download my borders function.
