How to save an image using imwrite with a filename from a variable

I am saving a frame from a video as an image. Both the image and video should have the same name. How can I save an image with a file name from a variable? The filenames are stored in the variable videos.name

    videos = dir('*.avi');
for i = 1:size(videos)
    [pathstr,name,ext] = fileparts(videos(i).name) 
    V = VideoReader(videos(i).name);
    oneframe = readFrame(V);
    imshow(oneframe)
    imwrite(oneframe, name, '.jpg')

end

Thank you very much!

The answer sounds trivial: Provide different file names. Prefer to open a new thread and to add any details about what your problem is.

Hi Nalini,

You can combine string values using square brackets. The syntax for imwrite using your variable names is as follows:

imwrite(oneframe, [name, '.jpg']);

Check your workspace to ensure name is the intended file name without a file extension.

Hope this helps
