Dear Sir,
i am trying to use imwrite to save some images i selected from my database to put them in a new folder
i used this : image2= imread(['C:\Database\',num2str(x(i)),'.jpg']);
imwrite(image2,fullfile(cd, strcat('C:\Results\',image2,'.jpg')));
would you guide me to solve this?
Thank you

fullfile(cd, strcat('Results\',num2str(x(i)),'.jpg'))

You missed the strcat() step, Jessica.

This is not valid:
fullfile(cd, strcat('C:\Results\',image2,'.jpg'))
While cd is the current directory, you cannot append the path 'C:\...'. Most likely you want:
fullfile('C:', 'Results', [image2, '.jpg'])
or directly:
['C:\Results\', image2, '.jpg']
to construct the file name.

Or (my favorite) use sprintf() to construct your base filename:
baseFileName = sprintf('Results %d.PNG', imageNumber);
fullFileName = fullfile(folder, baseFileName);
Note that I use PNG for lossless compression and better saved image quality, rather than JPG.
