Error using ==> SVD

[julietc]

Hi,
I'm having the following error

??? Error using ==> svd
Input to SVD must not contain NaN or Inf.

Error in ==> cond at 40
s = svd(A);

Error in ==> solve1 at 118
elseif bad_cond_flag && cond(fjac) > 1/sqrt(eps)

Error in ==> dynare_solve at 76
[x,info]=solve1(func,x,1:nn,1:nn,jacobian_flag,1,varargin{:});

Error in ==> steady_ at 120
[oo_.steady_state,check] = dynare_solve([M_.fname '_static'],...

Error in ==> steady at 54
steady_;

Error in ==> usmodelST1shocks at 474
steady;

Error in ==> dynare at 132
evalin('base',fname) ;

I have computed the residuals from the steady state guess and it looks ok. Any idea where the problem is?
Attached my code
Thanks!

Hi,

You have some NaN in the jacobian of your model.

You write "ewma(-1)^cmaw" while "ewma=0" and "cmaw=0": the derivative of this object is undefined. Similarly, you have "epinfma(-1)^cmap".

Best,
