I have this data which is given below (and a .dat file is also attaced: actual data is very large this is only a scaled-down version to give an idea).
Thsis data has three groups.
each group have ID, date, time and, location.
I want to import data into matlab, and I wannt to put data into a structures based on ID. I also need to extarct ID date and time from this file.
Currently I can import data, my imported data is in three coulmns but I cant figure out how to separate three groups.
