How do I get the Jacobian of my model?

The Jacobian elements are displayed implicitly in either the Equation listing (use Option Limrow = xxx) or the Column Listing (use Option limcol = xxx).

You can also use the convert “solver” to obtain the Jacobian: You “solve” your model with convert and this option file (you need at least GAMS 22.4 for this):


This will give you two files jacobian.gdx and dict.txt.
