cellArray = {};
Elements of a cell array can be anything, for instance variable-size vectors. Even the data types can be different, though that's not relevant to your question.
cellArray{1} = [1 2 3];
cellArray{2} = [single(4)];
cellArray{3} = false;
cellArray{4} = dsp.SineWave;
You can read the cell array the same way as writing it:
for i=1:length(cellArray)
cellArray{i}
end
Now if you store your starting and ending indices in an appropriate matrix (say 5x2), you can create your cell array of variable-size vectors iteratively in a for loop.
