I'm doing a predictive modeling research project and for my report I can't just explain that I input the data into MATLAB and it spits out a model for me after using classregtree. So does MATLAB use ID3, CART, C4.5 for creating trees? What is MATLAB's univariate splitting criteria?

classregtree uses the CART algorithm described in the Classification and Regression Trees book by Breiman et al.

I think you will find your answer in the documentation:
Splitting criterion:
But if you look at the references in the ClassificationTree.fit it cites the following:
[1] Coppersmith, D., S. J. Hong, and J. R. M. Hosking. "Partitioning Nominal Attributes in Decision Trees." Data Mining and Knowledge Discovery, Vol. 3, 1999, pp. 197217.
