Gekko 3.0 user manual

Return to chapter overviewNext page

Last modified: 15/3 2019

 

NOTE: New user manual design, ported to these formats: chm, html or pdf (new). Status regarding the user manual is the following. All pages have been read through, all visible errors have been corrected, and large parts of the pages have been rewritten. What is now lacking is to read through each page more thoroughly, among other things testing that the syntax and examples all work as intended. This second phase of renovating the Gekko 3.0 user manual is ongoing.  

 

Gekko Timeseries and Modeling Software is an open-source software system for handling and analyzing timeseries data, and for solving and analyzing large-scale economic models. See the Gekko homepage: www.t-t.dk/gekko.

 

The current 3.0 version is a beta version. So the current version is not completely stable yet, and the user should keep that in mind if using it for serious purposes. Not all of the capabilities of Gekko 2.4 have been ported yet. See the list of issues on this page:
