filelist = dir('*.jpg');
L = length(filelist);
for i = 1:60
CurrentImage{i} =imread([ num2str(i) '.jpg']);%read image based
%%code here
%%implement preprocessed image onto current image
Complete_Output{i} = CurrentImage{i} + FinalOutput;
%%Write complete_output into workspace
imwrite(Complete_Output, {i}); %error here

Currently i am reading 60images from local files, after preprocessing, i need to save all 60 images into ...

@Ou Jin Sheng - imwrite writes data to a file as
imwrite(dataArrayOrMatrix, 'filename')
Your code is doing something different
imwrite(Complete_Output, {i}); %error here
I suspect that you want to do something like
imwrite(Complete_Output{i}, sprintf('updatedImage%d.jpg',i));
or something similar to write the updated image to file (not the workspace).
