I have a matrix of 47 lines and 3 columns which show the EOFs at 47 measurement places. I also have two vectors with the latitude and longitude at which the stations are located I want to plot 3 maps, one for each EOF in which 47 points are shown
for plotting them I use geoshow as:
ax = worldmap('angola');
load coastlines
setm(ax, 'Origin', [0 20 0])
plotm(coastlat,coastlon);
hold on
for i=1:47
lat=latitude(i)
lon=longitude(i)
value=EOF(i,1)
geoshow(ax, lat, lon, 'DisplayType', 'point')
end
I have no idea on how can I represent the values in the variable value on the map. Any help is welcome. Thanks for reading.

https://en.m.wikipedia.org/wiki/Empirical_orthogonal_functions would seem to be the appropriate meaning of EOF here?
