Can you share the code and the badOfWords to provide a little more elaboration?

docum is a sting with 68 words and the code for bOW is the follwoing:

bag = bagOfWords(docum)

And the result is as stated:

bag =

    data = cat(1, image_patches,labels);

That code is overwriting all of data each iteration.

It looks to me as if data will not be a vector, but I do not seem to be able to locate any hellopatches() function so I cannot tell what shape it will be. As you are not doing imresize() I also cannot be sure that all of the images are the same size, so I cannot be sure that data will be the same size for each iteration. Under the circumstances you should be considering saving into a cell array.

Note: please do not post the same query multiple times. I found at least 3 copies of your query :(
