Error message

Hello all,
I try to estimate some model but the dynare gives me the error below : I don’t know what is the problem here.I checked my data file and everything seems correct. Thank you for your answer.

??? Error using ==> eig
Input to EIG must not contain NaN or Inf.

Error in ==> dr1 at 256
dr.eigval = eig(transition_matrix(dr));

Error in ==> resol at 97
[dr,info,M_,options_,oo_] = dr1(dr,check_flag,M_,options_,oo_);

Error in ==> dynare_estimation at 275
[dd,info] = resol(oo_.steady_state,0);

Hi, You have NaNs or Infs in the transition matrix of the state equation. This may be caused by a singularity in the jacobian matrix (for some values of the deep parameters). We cannot say more if you do not post a mod file so that we can reproduce your problem.

Best, Stéphane.
