MathWorks has examples like this one using classifiers from the Statistics and Machine Learning Toolbox to work on text data. The main problem with converting this to using a naïve Bayes algorithm is that fitcnb is not optimized to work with high-dimensional sparse data, such as a basic word count.
To alleviate that problem, use a dimensionality reduction step, such as fitlsa.
