I built this wrapper to facilitate processing when performing modal analysis in arbitrary data sets. The wrapper accepts an N-D input matrix (Big_X) that has its first dimension as time and the other dimensions can be whatever the application requires.

The wrapper (hopefully) reduces the barrier of entry when doing these calculations, as building your own DMD function from scratch is quite time-consuming. Although there indeed are other functions like this one on Matlab Exchange, I often found that the lack of easy-to-use outputs was sometimes hindering my progress. So hopefully you will also find this useful!

Attached an usage sample and a small data set of a shedding cylinder to test the usage. Thanks to Prof. Louis Cattafesta from Florida State University to inspire me to produce this. If you have any requests please let me know.
