Dear All
I have a TLE(Two-line element) and I got the following code to structure the data.
fid=fopen('2B.txt');
A=textscan(fid,'%s','HeaderLines',5);
Data=reshape(A{1}(1:end-3,:),9,[])';
fclose(fid);
format long g;
l1=Data(1:2:end,:);
l2=Data(2:2:end,:);
I have the below TLE for a satellite, for example I want to access each and every value of (1,3) which is 96063A. In this 96 is year of launch, 06 is month of launch and so on. With the above code the data of each row and column is stored in individual cell. how can I access each value of the whole file.
Thanks

I'm not completely sure what you mean, but to access the induvidual characters in each cell you just had to index within that cell:
Data{1,3}(1:2) %96
Data{1,3}(3:4) %06
Data{1,3}(5:6) %3A
Note that the numbers are still strings not numeric, you can use str2double or str2num to convert.

And how can I display and store in a single variable of all the elements of all rows and 4th column as they are changing in every line?
