Join matrices in for loop

I am importing several files in matlab which are in csv format. Each of these files has two columns. So when I import the first one I create a matrix with two columns. therefore I would like to join this 2 column matrices in one matrix. I would like to do that in a for loop.
My code is the following:
files=dir('*.csv');
Data=[];
for i=1:length(files)
fid(i)=fopen(files(i).name);
files(i).values=textscan(fid(i), '%f %f','delimiter',',','HeaderLines',20,'MultipleDelimsAsOne',1);
A=cell2mat(files(i).values);
end
In my code each time the matrix A is a two column matrix. So I would like to join all the A matrices.

Thank you very much for the answer. It was so easy to implement....
Only one notice it should be
A=[A cell2mat(files(i).values)];
The semicolon must be removed
