Assuming that the intensities are numeric and that each element in the cell array is a matrix of 1x1000 dimension, then why not just concatenate all of the data together into a 100x1000 matrix, where each row in the matrix is the 1000 intensities for a single lund cell?
lundCellData = zeros(100,1000);
for k=1:100
lundCellData(k,:) = cellArray{k}; % cellArray is the 1x100 element cell array
end
imagesc(lundCellData);
This will plot the time data along the x-axis, and the lund cell numbers along the y-axis.
Try the above and see what happens!
