Hi friends,
when I run my model, appear these errors:
Error using print_info (line 52)
One of the eigenvalues is close to 0/0 (the absolute value of
numerator and denominator is smaller than 1e-6)

Error in check (line 76)
print_info(info, options.noprint);

Error in MODEL (line 364)
oo_.dr.eigval = check(M_,options_,oo_);

Error in dynare (line 120)
evalin('base',fname) ;


When I type message "model_diagnostics(M_,options_,oo_)" in MATLAB, appear this message:

model_diagnostic: the Jacobian of the static model is singular

As the last line
The presence of a singularity problem typically indicates that there is one
redundant equation entered in the model block, while another non-redundant equation
is missing. The problem often derives from Walras Law.

says, this is a problem with you model. People here won't be able to help you as they don't know your model and we rather provide technical support.
