You can use plot() to plot matrices in a geographic axes
Any easy workaround is to (a) create a GeographicAxes object and (b) add lines to it using the plot function instead of the geoplot function.
But first a quick correction: It looks like you want to connect each of 3 points to a common point at (lat=2, lon=48). However, plot creates a line for each column in the input matrices, not each row, so I think you have your inputs transposed. Starting again, and forming 2x3 matrices LAT and LON, we have:
lonFrom = [48 48 48]; % Longitude From
latFrom = [2 2 2]; % Latitude From
lonTo = [52 41.7 40]; % Longitude To
latTo = [13 12.5 -3.5]; % Latitude To
LON = [lonFrom; lonTo];
LAT = [latFrom; latTo];
For reference, here are the lines in an ordinary axis using plot:
figure
plot(LON,LAT)
Finally, create a GeographicAxes in advance using geoaxes, then pass it to plot as the first input:
figure
gx = geoaxes;
plot(gx,LAT,LON)
Note: Latitude comes before longitude when plotting into a GeographicAxes, whether using geoplot or plot (or line, geoscatter, scatter, or text).
