Singular Jacobian


I’m running a model and getting the following message.

DYNARE_SOLVE (solve_algo=2|4|12): the Dulmage-Mendelsohn decomposition returned a non-square block. This means that the Jacobian is singular. You may want to try another value for solve_algo.

Not quite sure what it means or how to interpret it.

As it says, the solve_algo in steady will not work. Use a different value.
