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
