MATLAB Functions for Daymet Tiles

A toolkit of two MATLAB functions that download and merge Daymet tiles has been contributed by Dr. Chao Li, PhD at Carnegie Institution of Science at Stanford University. These are hosted on the Tools page of the Daymet website. One function allows a user to download data directly into MATLAB for separate Daymet variables. Another function merges adjacent Daymet tiles. Dr. Li has also provided a demo script for greater details about how to use the functions. Many thanks to Dr. Li for his contribution.
