I have a list of gauge stations like this
Code X Y
12345678 -35.74 -18.24
01234567 -38.71 -18.42
...
And a list of disasters events like this
Date X Y
2016/1/1 -35.73 -18.24
...
I need to find the nearest gauge station for each event, than add the code of corresponding station as a row on disaster matrix:
Date X Y near_station
2016/1/1 -35.73 -18.24 12345678
...
Any suggestions how can I do this on MatLab?

There is a built-in Matlab function dsearchn. Alternatively, you can write your own code using an approach similar to the one given for another question here.
