Hi, we get a text file
like the one i have attached and are asked to determine a suitable way to read the data in matlab. There are also variables reaching 2000 seconds. Thank you

You would have to use the fscanf function in order to ensure that you do not read the associated text. Thereafter you can employ loop methods to separate you data into time,latitude and longitude respectively.

readData=textread('YourFile.txt','%s')
This will remove the gap inbetween and give you all the data as strings. Once you get the string you can only take the required string for eg. The time data might be repeated in every 2nd ,9th, 16th etc with constant gap.
Use a for loop to get this data and use str2num to change it to a number.
Hope this solves your problem.
