When I tried ti run this code which I copied from MATLAB documentation:
setDir = fullfile(toolboxdir('vision'),'visiondata','imageSets','cups');
imds = imageDatastore(setDir);
imageIndex = indexImages(imds);
I got this error
Error using indexImages
Expected input number 1, imgSet, to be one of these types:
Instead its type was matlab.io.datastore.ImageDatastore.
Error in indexImages>parseInputs (line 125)
validateattributes(imgSet, {'imageSet'},{'scalar'}, mfilename, 'imgSet',1);
Error in indexImages (line 99)
[bag, params] = parseInputs(imgSet, varargin{:});
Why? could anyone please clarify? I'm pretty novice in MATLAB, so I would be grateful if you give me very clear answer. Thanks.

In R2016a and earlier, indexImages did not permit an imageDataStore to be passed to it. You are looking at R2016b documentation but trying to operate with an earlier version. The R2016a documentation for the function is at http://www.mathworks.com/help/releases/R2016a/vision/ref/indeximages.html
