joining two arrays to make a longer one

If I have two arrays, lets say the first is called a and the second is called b, I am aware of the fact that I can combine them with the command A=[a;b] to get a longer array
the problem I have got now is the following: I have two matlab files (let's say the first one is year 2002 and the second one from year 2003) which are saved in my computer and wich I would like to load, what is no big deal. Ich matlab file consist of 8 vectors which are called F,K,PC,Price,T,VIX,date,r
loading this is no problem, but as soon as I an loading both files, because the arrays in the files have the same name, the second file is overwriting the first one is there a way to write a code in a script which loads both files and combines them the way I mentionned above without overwriting the first file?

You aren't using load correctly. You need to load each into its own structure
storedStructure1 = load(filename1);
storedStructure2 = load(filename2);
% Get theResults (or whatever) from each
theResults1 = storedStructure1.theResults;
theResults2 = storedStructure2.theResults;
% Concatenate
theResults = [theResults1; theResults2];

If all vectors are column vectors, do the following:
data = [] ;
for f = 1 : nFiles
% Load file f:
% ... whatever you are doing to load the file.
% CAT to data array:
data = vertcat(data, [F,K,PC,Price,T,VIX,date,r]) ;
end
if these are row vectors, just transpose them. If it is a mix and you don't want to investigate, just read them linearly ( => column ):
data = vertcat(data, [F(:),K(:),PC(:),Price(:),T(:),VIX(:),date(:),r(:)]) ;

What I still do not reallly understand is how that is working, or in other words which element is allowing me to load the data without overwriting them, could you explain that to me? Is seems as 2002 is stored in ld, but I do not get what ld is and how it's done then
