Change name of variable at each iteration of a for loop

I am using Matlab to do image processing on 3D image stacks. I am importing several image stacks at the same time, then doing work on them. I want to call the first image stack "bkg0" and the second "bkg1" etc. until I have imported all of the images. The number of images, however is variable depending on the data set that I've collected. Is it possible to do this?

The idea I want is something like this:

for i=1:size(ls,1);
bkg'num2str(i)'= load image;
end;

where each image is a 3d image stack, and the 'num2str(i)' section goes from 1 to the size of the listed data (ls).

Any ideas?

You can read them all into cells of a cell array. The name of the cell array stays the same, you just use a different index (the loop index) to stuff the image into different cells in the cell array. Something like:

for k = 1 : size(ls,1);
  bkg{k} = imread(fullFileName);
end

I don't see how that will do anything useful at all for Kolbein ??
