The model doesn't determine the current variables uniquely

[alexmen]

Dear all,
I am duelling with a two sector model,
after computing the steady state, Dynare produces the following error message:
Warning: Matrix is singular to working precision.

??? Error using ==> print_info
The model doesn't determine the current variables uniquely

Is there a way to understand what kind of problem could this be and how to fix it?
Thanks in advance.

What the message means is that, given expectations and past value of the variables, it isn't possible to determine the current value of the endogenous variables uniquely.

In a two sector model, I would suspect that two equations are linear combination of each other or that you have a redundant market clearing condition.
