This standalone version of the EOF function is no longer being maintained. It still works fine, but you'll find the most up-to-date version in the Climate Data Toolbox for MATLAB here: https://www.mathworks.com/matlabcentral/fileexchange/70338. If the eof function has been useful for you, please cite our Climate Data Toolbox for MATLAB paper!

This function simplifies the process of applying Empirical Orthogonal Functions (spatiotemporal principal component analysis) to 3D datasets such as climate data. EOF analysis is not terribly difficult to implement, but much time is often spent trying to figure out how to reshape a big 3D dataset, get the EOFs, and then un-reshape. This function does all the reshaping for you, and performs EOF analysis in a computationally efficient manner. The analysis method is a streamlined and optimized version of Guillame MAZE's caleof function, method 2.
