I want to make a simple program that ask image file from user, resize it and then it ask from user where to save it. Everything went right except this imwrite command. i dont know to use it properly . below is the code.
figure(1); imshow(x); title('1024*1024 Image')
figure(2); imshow(y); title('512*512 Resized Image');
[filename, pathname] = uiputfile('*.jpg', 'Save Picture as');
imwrite([y, filename, pathname]);
