Use menu(), then depending on which button was selected, use sprintf() to write the proper extension into the filename. Let me know if you can't figure it out and I can give a demo.

If you're having trouble, here is the code:
folder = 'C:/Users/ankita/Documents';
baseFileName = 'myOutputImage';
button = menu('Use which format for the image file?', 'PNG', 'BMP', 'TIF', 'JPG');
if button == 1
extension = 'PNG';
elseif button == 2
extension = 'BMP';
elseif button == 3
extension = 'TIF';
else
extension = 'JPG';
end
% Append extension to the base file name.
baseFileName = sprintf('%s.%s', baseFileName, extension)
% Prepend the folder to get the full file name.
fullFileName = fullfile(folder, baseFileName)
imwrite(imageArray, fullFileName);
