residuals of static equations NaN

[miti]

Hi there,

I am trying to run this model in dynare. I have a separate steady state file to compute the steady state, but every time I try to run it it gives the following error message. I have attched the dynare and the steady state file. please let me know if you can say what the problem might be.

The steadystate file did not compute the steady state

Your steady state file is not correct. You cannot simply paste a second function into the middle of a different function.
Please use an anonymous function of the form

Code: Select all

function [ys,check] = try4_steadystate(ys,exo)
% function [ys,check] = try4_steadystate(ys,exo)
% computes the steady state for the NK_baseline.mod and uses a numerical
% solver to do so
% Inputs:
%   - ys        [vector] vector of initial values for the steady state of
%                   the endogenous variables
%   - exo       [vector] vector of values for the exogenous variables
%
% Output:
%   - ys        [vector] vector of steady state values fpr the the endogenous variables
%   - check     [scalar] set to 0 if steady state computation worked and to
%                    1 of not (allows to impos restriction on parameters)

NumberOfParameters = M_.param_nbr;
for ii = 1:NumberOfParameters

  eval([ paramname ' = M_.params(' int2str(ii) ');']);
end
