Problem with analytic_derivation

Hello,

I have problem with analytic_derivation calculation. I use dynare 4.3.1, matlab 7.3.0.267.

I have following error message:

Matrix “d” has 3 dimension (within sylvester3 or getH). My version of matlab don’t understand what is product of 2D matrix with 3D matrix. I don’t understand what should be result of such product too. Could you help me to understand what result should be?

Only works for stationary models without missing observations.

As I understand, it’s not a problem of missing observation. Code of getH function creates 3D matrix. Code of sylvester3 tries to make product of this matrix and always think that d is 2D matrix.

elem = zeros(m,m,param_nbr); d = elem; for j=1:param_nbr, elem(:,:,j) = (Dg0(:,:,j)-Dg1(:,:,j)*A); d(:,:,j) = Dg2(:,:,j)-elem(:,:,j)*A; end xx=sylvester3(a,b,c,d);

Is correct idea of following understanding?

    for j=1:param_nbr,
        elem(:,:,j) = (Dg0(:,:,j)-Dg1(:,:,j)*A);
        d(:,:,j) = Dg2(:,:,j)-elem(:,:,j)*A;
        xx(:,:,j)=sylvester3(a,b,c,d);
    end

Could you post the mod-file

I’m sorry for delay. This model isn’t finished.
