Dear members
I have the following data from a text file:
1 23948U 96040A 96214.98321868 .00000118 00000-0 00000+0 0 464
2 23948 0.0614 236.9184 0001375 279.5530 174.2840 1.00271670 256
In line 2 the term '0001375' I want to read it as '0.0001375' but actually when I read this term it is read as '1375'.
Any solution to this?
I am using the following code to read it.
ecc=str2double(L2(5)); %L2 is line 2 (I have split the lines as L1 and L2)

Why is it wrong in the first place? What wrote out this incorrect data? Can you fix it there so it doesn't get written out incorrectly in the first place? Also, what do you want to do with terms that have letters (U, A like line #1) attached to them?

Actually it is a TLE (Two Line Element) Data. And it comes as it is. I have a huge data to be read therefore I needed a way to read them in a desired way. The term I am referring to is eccentricity of the orbit. More info at http://www.celestrak.com/NORAD/documentation/tle-fmt.asp
