Loading multiple datafile of different sizes

I have 30 measurement files that I would like to work with which are time dependent and not of equal length. I was wondering what the best way to load these in to plot them without dealing with each one individually. The 30 files are over a 6 day period and I want to plot them by day so they will not all be on one graph.
I started with a loop, but ran into trouble since the lengths of the files are not equal.
%%Load files
for I = 0:29
filename = sprintf('Tension&CBResistance_%i.lvm',I)
TCB(I+1,:,:) = load(filename);
end
If possible, I also rather not declare some huge 3D matrix just to pad the ends of data arrays with zeros or NaN.
Thanks:)

Store them in a cell array or in a structure, if you can't concatenate.
for I = 0:29
filename = sprintf('Tension&CBResistance_%i.lvm',I)
TCB{I} = $load(filename);
TCB.(filename) = load(filename);
end

I'm not sure I understood all the code you introduced, but this seems to work for loading the files.
for I = 0:29
filename = sprintf('Tension&CBResistance_%i.lvm',I)
TCB{I+1} = load(filename);
end
Now my question becomes how to plot them all without listing each one.
If they were arrays, I could would do
plot(TCB(1:6,:,1), TCB(1:6,:,2))
but this doesn't seem to work for cells. I tried
plot(TCB{1:6}(:,1),TCB{1:6}(:,2))
but get a "??? Bad cell reference operation." error
