I'm using MATLAB R2014b version with computer vision toolbox. I'm trying to generate classifiers with different types of extractors to analyse handwritten words, and for that i'm making use of bagOfFeatures function. MATLAB doesn't have a SIFT extractor code but it's possible to implement it or use David Lowe's version. How can i use this SIFT extractor (and detector) with the bagOfFeatures function?
Thanks

If you can upgrade to a later version (R2015a or higher), you can use the 'CustomExtractor' name-value pair to do this. Unfortunately, this wasn't part of R2014b.

Is there a Custom Extractor file available for SIFT feature extraction?

SIFT is still patented by the University of British Columbia for a few more years. I believe the Computer Vision System Toolbox uses SURF instead.
