Generalized Schur (QZ) error coding

Stochastic simulations
1

Dear Dynare experts,

I got the following issue:

The generalized Schur (QZ) decomposition failed. For more information, see the documentation for Lapack function dgges: info=355, n=353. You can also run model_diagnostics to get more information on what may cause this
problem.

Could someone please explain the meaning of ‘info=355, n=353’ in this error message? is there a list of errors (I couldn’t find in the manual).

Thanks a lot,

Best regards

This is a LAPACK error message related to the number of eigenvalues. It usually indicates that there is a fundamental problem with your model, often a timing issue.
