Distinguish european voyages from coordinates

Hello everyone,
I have a large dataset with coordinates and name of arrival and departure ports. How can Matlab identify if the ports are in Europe or not? Is there a way from coordinates to distinguish voyages into Europe and outside of it?
Thanks, Vanessa

Hello Vanessa,
Firstly, classify this large dataset into 2 classes: Inside the europe and outside the europe.
Then perform matching for any of the data points. If that data point lies in "Inside the europe" class then particular port is in europe otherwise not.

There are so many algorithms to perform classification. Now, which one to choose, depends on your data and its type.
It will be easy for someone to give proper answer of your question if you show you database.

The names of the arrival ports seems to be much easier. How many different ports do you have? What exactly is "large"?
Did you take the time to ask an internet search engine already? Perhaps: https://www.google.de/search?q=Find+country+belonging+to+GPS+coordinates . This migth be useful: https://developers.google.com/maps/documentation/geocoding/start?csw=1

Have a look at https://www.mathworks.com/matlabcentral/answers/129963-generating-50-random-locations-inside-geo-map-data#answer_268603 where Kelly shows how to test whether a point is within a given shape.
Combine that with a shape file for Europe, perhaps one of the ones mentioned at https://gis.stackexchange.com/questions/177741/looking-for-a-free-shapefile-of-the-european-countries
