I need to save images in a loop and also need to assign specific names to them for which I was using the following, which worked fine :

imwrite(view,sprintf('view_%d_%d.png',i,j)); %where view is the image data to be stored

But I also need to save them in specific folders but positioning the folder pathname is giving errors.

imwrite(view,^,sprintf('view_%d_%d.png',i,j),^); %tried putting pathname at locations with ^

> Error in imwrite (line 418) [data, map, filename, format, paramPairs] = parse_inputs(varargin{:});

What would be the correct syntax?

foldername = 'NameOfFolderGoesHere'
filename = fullfile(foldername, sprintf('view_%d_%d.png', i, j));
imwrite(view, filename);
