Hello!
I ran my model and I got the expected outcome but unfortunately with the error message below:
Warning: Matrix is close to singular or badly scaled.
Results may be inaccurate. RCOND = 4.238587e-064.
> In evaluate_steady_state at 76
In resol at 108

How can I solve this problem and get the best result?
Adding one more equation to my model, I got this message:
Warning: Matrix is close to singular or badly scaled.
Results may be inaccurate. RCOND = 1.179317e-063.

and the program couldn't run. I mean I did not get the expected outcome. I hope this may come from the initial value for the endogenous and exogenous variables.
How best can I find the steady state that satisfies the rank condition?
Thanks
