Displaying the Jacobian matrix

Perfect foresight simulations

Hi,
I have the following error when I run my non-linear model: The Jacobian matrix evaluated at the steady state contains elements that are not real or are infinite.

I would like to display this Jacobian matrix in order to solve by myself this problem. Is it possible ?

Best,
Jonathan

Hi, after the error, first run

Then run

where example1 was the name of the mod-file. Change this accordingly. You should use Matlab’s debugging mode to find out where the problem is.

hi, I have the same problem as yours. Did you successfully solve your problem?

Try using

options_.debug=1

or provide your mod-file.

Hi, I am also getting the “The Jacobian matrix evaluated at the steady state contains elements that are not real or are infinite.” error. Please advise.

I am getting

Impossible to find the steady state (the sum of square residuals of the static equations is 0.0000). Either the model doesn’t have a steady state, there are an infinity of steady states, or the guess values are too far from the solution
