How can i save the number of images stored in a cell array to my folder ?

How can i save all the images stored in a cell array in the matlab directory path,so that i can use them further.What is the syntax of writing multiple images from cell array to the system in jpg format?please help.

for i = 1:numel(myCellArr)
  fileName = sprintf('image_%04d.jpg');
  imwrite( myCellArr{i}, 'fileName.jpg' );
end

I have used this code but it is not saving all of my images stored in cell but only the last image.'please help me to obtain the desired result.

Almost correct:

for i = 1:numel(myCellArr)
  fileName = sprintf('image_%04d.jpg', i);  % "i" required
  imwrite( myCellArr{i}, fileName);
end

In your code, you saved the files with the name 'fileName.jpg', but you want tzhe variable called "fileName".

A hint: Do not rely the current directory to be fixed. A graphics or timer callback can change the directory. Better use absolute file names:

folder = 'C:\Temp';  % Or whatever
for i = 1:numel(myCellArr)
  fileName = fullfile(folder, sprintf('image_%04d.jpg', i));
  imwrite( myCellArr{i}, fileName);
end
