How to import array of different size in structure

Hi,

I have a a few text files such as text1.txt, text2.txt, text3.txt...

Inside each of these text files is a table matrix looks like this:

 tex1.txt:
 time     CCB       CCC

 0.0       -1        0

 0.1       -2        7

 0.2       -3        8

 0.3       -4        9

 0.4       -5        6

 text2.txt:
 time     CCB       CCC

 0.0       -9        3

 0.1       -8        3

 0.2       -7        3

 0.3       -1        2

 text3.txt:
 time     CCB       CCC

 0.0       -8        2

 0.1       -8        0

 0.2       -66       1

Notice that each textfile has the same number of column however different row. In other word, they are of different size.

I start with,

 newData=importdata(fileToRead,DELIMITER,HEADERLINES); 
%(I have already take care of looping and headerlines count, so dont worry about it. The actual file has differnet number of headerlines too)

And then:

 colheaders=genvarname(newData.colheaders)
 for a=1:3   
     for i=length(colheaders)
         dataByColumn(a).(colheaders{i})=newData.data(:,i);
     end

     vars=fieldnames(dataByColumn(a));
     for i=1:length(vars)
         assignin('base',vars{i}(a),dataByColumn(a).(vars{i}));
     end
  end

(*Notice at the assignin line, assignin doesn't seem like accepting any indexing)

I want my end result to look like this:

 time={[5X1] [4X1] [3X1]}

and the rest as well. So that I can extract individual column by:

 time{1}
 time{2}
 time{3}

Is there any possible to do this?Please advise.

for k=1:3
  a=importdata(sprintf('text%d.txt',k),' ',1);
  v=a.data
  time{k}=v(:,1)
end

Sorry, I did not declare my question clearly. The actual file names are much more complex and there are no intuitive relationship in the naming of the files, Also the column headers in actual text are much more than three columns. Some files contain up to 50 columns with different headers. So I need an automatic way of generating the variables from the header.

Do you want just the first column?

%Example
YourFolder='E:\matlab'
f=dir([YourFolder '\*.txt'])
for k=1:numel(f)
  a=importdata(f(k).name,' ',1);
  v=a.data;
  time{k}=v(:,1);
end
