hi,
i am supposed to plot latitude and longitude for the given data but longitude and latitude are given as 9-digit numbers and 8-digit numbers respectively. for example;
longitude 127065072 and latitude 37479232. i have a complete table filled with these kind of longitudes and latitudes. can anyone help me understand how to change these numbers to DMS and decimal degress for the whole table?

My guess would be that it already is a decimal degree, but without the decimal point. Does your data make sense to you if you divide these numbers by a million?

I don't see any "simple" method. I would recommand you to use the following idea:
% get each digit in char array
digits = dec2base(myNumber, 10) - '0'
% reconstruct degrees, second... (in char)
% transform back in numbers
degree = str2double(degree_char)
...
I don't know how works the longitude and latitude description. So I cannot help you more but you have the basic idea.
