File Information
Description

This package provides a Matlab-based implementation of the Ecopath algorithm (part of the popular fisheries ecosystem modeling tool Ecopath with Ecosim (http://www.ecopath.org), as well as a few functions for further analysis and visualization of an Ecopath-style food web.

This software is intended for people already familiar with the Ecopath concept who wish to perform that particular calculation, as well as related analysis of food web properties, outside of the GUI environment provided by the original EwE software.

Updates
03 Jun 2014 1.1

- Major overhaul to the createensemble routines: more flexibility, new sampling options, and improved efficiency
- mdb2ewein now uses dataset arrays, can return all data in the mdb file
- support for multi-stanza groups

03 Jun 2014 1.2

Corrected FEX image

18 Aug 2015 1.3

- Calculations are now robust to all potential input models, including those with multi-stanza groups.
- Completed implementation of the generalized inverse.
- Corrected bug in mdb2ewein where tables with spaces in their name were misinterpreted

30 Jun 2016 1.4

Updated description to reference github readme.

30 Aug 2016 2.0
