while extending the identification toolbox I often run into the need to compute a 2d matrix with a 3d array. That is, assume `A is [m x n]`, `B is [n x o x p]` and I need to compute `C(:,:,j)=A*B(:,:,j)`. Currently, I simply run a for loop (as p is dimension of parameters and hence not so large), i.e. the minimal matlab code looks like
```
for j=1:size(B,3)
C(:,:,j) = A*B(:,:,j);
end
```
Is there a more efficient way/trick to do so?Hi,

I was wondering if somebody can explain to me the structure of kstate? I am aware that using this is depreciated, as this is a reminiscence of old dynare versions where we did not create auxiliary variables for leads and lags greater than one, but still I find it is used in several functions dealing with e.g. the perturbation solution or identification toolbox.
In any case, I still have problems to get the hang of this. So maybe someone can help me out, given the following simple example:
```
var Y C K A;
varexo eps_A;
parameters alph betta rhoA sigA;
alph = 0.35; betta = 0.99; rhoA = 0.9; sigA = 0.6;
model;
C^(-1)=alph*betta*C(+1)^(-1)*A(+1)*K^(alph-1);
K=A*K(-1)^alph-C;
log(A)=rhoA*log(A(-1))+sigA*eps_A;
Y = A*K(-1)^alph;
end;
```
As I understand, my state variables are K and A, i.e.
- the declaration order is Y C K A
- the DR order is Y K A C
- lead_lag_incidence is equal to
| | Y | C | K | A |
|------|---|---|---|---|
| t-1 | 0 | 0 | 1 | 2 |
| t | 3 | 4 | 5 | 6 |
| t+1 | 0 | 7 | 0 | 8 |
where the number corresponds to the corresponding column number in the dynamic files (i.e. derivative wrt the variable)
Now, the kstate variable is given by:
| | | | |
| ------ | ------ | -----|--|
| 3 | 3 | 4 | 0|
| 4 | 3 | 3 | 0|
| 2 | 2 | 0 | 1|
| 3 | 2 | 0 | 2|
but I do not understand this. As far as I see, there is only one comment in set_state_space.m:
```
% composition of state vector
% col 1: variable; col 2: lead/lag in z(t+1);
% col 3: A cols for t+1 (D); col 4: A cols for t (E)
```
but what is the meaning of z(t+1), A, D and E or to which state space representation do these correspond to?
Thanks!Hi,

If we use numerical derivatives (kronflag=-1|-2) the computations are correct.
To replicate the bug, I looked at the Brock and Mirman model (i.e. RBC model with log utility and full depreciation), where we know analytically the policy functions, i.e. also the Kalman transition matrices of a first-order approximation (A, B and Om) analytically. Hence, using symbolic computations it is possible to compute the true `d2A` and `d2Om` and compare the values to dynare.

```

I think the reason is that in `dynare_identification` in line 155/157 `prior_draw(bayestopt_, options_.prior_trunc, false)` is called once to initialize the following persistent variables in `prior_draw`:
```
persistent p6 p7 p3 p4 lb ub

persistent uniform_draws gaussian_draws gamma_draws beta_draws inverse_gamma_1_draws inverse_gamma_2_draws weibull_draws
```
Once we have that, `prior_draw()` generates a new draw. At least this is the ways it works in Matlab and the test file runs through.
However, in Octave the persistent variables do not get set for some reason, and hence `gamrnd` is called with undefined inputs, as far as I can see.I noticed that running `tests/identification/as2007/as2007.mod` of the master branch with Octave (ver. 4.4.1) does not work with the following error:

See e.g. line 85 of `AIM_first_order_solver.m`:
`nba = nd-sum( abs(dr.eigval) < qz_criterium );`
However, it appears that in `dyn_first_order_solver.m` it is instead a threshold on the squared absolute value of `dr.eigval`. See line 190 of `dyn_first_order_solver.m`:
`[err, ss, tt, w, sdim, dr.eigval, info1] = mjdgges(E, D, DynareOptions.qz_criterium, DynareOptions.qz_zero_threshold);`
line 31 of `mjdgges.c`:
`return ((*alphar **alphar + *alphai **alphai) < criterium **beta **beta);`
and line 107 of `mjdgges.c`:
`criterium = *mxGetPr(prhs[2]);`
The eigenvalues are `( alphar[j] + alphai[j] * 1i ) / beta[j]` according to [the MKL manual](https://software.intel.com/en-us/mkl-developer-reference-fortran-gges). Thus, it seems that this code is comparing the **squared** absolute value of the eigenvalue to `qz_criterium`.
The easiest fix would be to replace line 190 of `dyn_first_order_solver.m` with:
`[err, ss, tt, w, sdim, dr.eigval, info1] = mjdgges(E, D, DynareOptions.qz_criterium .^ 2, DynareOptions.qz_zero_threshold);`
so you're comparing squared to squared.I was under the impression that `qz_criterium` was intended to be a threshold on the absolute value of `dr.eigval`. See e.g. line 85 of `AIM_first_order_solver.m`:

I am solving a large model. The model is solved successfully on Mac up to 5th order approximation. When I try solve the model on Windows, or Linux server, it solves 3rd order in seconds, the program is "killed" by the system or by the program at 4th order after a few seconds of running. The cpu utilization is below 40% when killed, and memory usage is minimal. There is no other error message, except "killed" at the end. There is no issue solving a small model up to 5th on windows or linux. I would appreciate any explanations, remedies, or suggestions. Thanks.

The cpu utilization is below 40% when killed, and memory usage is minimal. There is no other error message, except "killed" at the end. There is no issue solving a small model up to 5th on windows or linux. I would appreciate any explanations, remedies, or suggestions. Thanks.

Hi @rattoma , I just noticed a bug in the identification toolbox when only checking for unidentified parameters without any other parameters, as Dynare prints that all parameters are identified even though the figures etc do not suggest so. This is probably just a small bug in the display function.
To replicate the bug (I use Dynare unstable from June, 3 and Matlab R2017b):
1) Open kim2.mod in the test files for identification
2) Change
>estimated_params;
alph ,uniform_pdf,0.6,0.04,0.5,0.7;
//betae ,uniform_pdf,0.99,0.004,0.98,1;
//delta ,uniform_pdf,0.0125,0.001,0.01,0.015;
phi ,uniform_pdf,0.5,0.2,0,10;
theta ,uniform_pdf,0.3,0.1,0,10;
dumpy ,uniform_pdf,0.5,0.2,0,10;
end;
to
> estimated_params;
//alph ,uniform_pdf,0.6,0.04,0.5,0.7;

theta ,uniform_pdf,0.3,0.1,0,10;
//dumpy ,uniform_pdf,0.5,0.2,0,10;
end;
That is, only include colinear parameters.
3) Run "dynare kim2" and the output is

Sébastien VillemotSébastien Villemothttps://git.dynare.org/Dynare/dynare/-/issues/1625Discuss implementing a steady_state_relation-block2019-12-03T14:19:24ZJohannes Pfeifer Discuss implementing a steady_state_relation-blockSteady state finding in large economic models is hard. Currently, the user needs to manually implement a full steady state or reduce the problem and then call a solver. See e.g. https://forum.dynare.org/t/how-to-solve-steady-state-in-large-scale-dsge-models/12185/2
I wonder if it would be useful and feasible to introduce something like a `steady_state_relation`-block that allows specifying analytical steady state relations that Dynare could use in the `_static`-file to substitute out some variable and thus reduce the size of the problem (essentially introducing a model-local variable for the static model). An example would be
```
steady_state_relation;
u=1;
R=1/beta;
Pi=1;
i_nom=R*Pi;
I=delta*K;
end;
```
Combined with `initval` this would make finding a steady state much easier.Steady state finding in large economic models is hard.

as instructed in this issue thread: https://github.com/DynareTeam/dynare/issues/1490
The example I found the aforementioned issue on previously included some empty strings. In this Dynare Unstable, these seem to result in an incorrect pre-processor error.
Saving the following three lines is a MOD file generates a pre-processor error in this version:
@#define StringArray = ""
parameters p;
p = 1;
However, if you put something inside the double quotes, it runs fine. It also runs fine on Dynare 4.5.5 even with the empty string.
