Dynare forums

Hi,

I'm trying to use dynare. When I open le exemple1's manual, I have a error.

This is it

dynare C:\dynare\4.0.4\ejemplos\example1.mod

Configuring Dynare ...

[mex] Sylvester equation solution.
[mex] Kronecker products.

??? Error: Unexpected MATLAB operator.

Error in ==> dynare at 103
evalin('base',fname) ;

I have not idea about what's happening. Help please!!

Hi Véronica, I tried your mod file and was unable to reproduce the eror message (even if you introduced some "bugs" in the mod file). Your problem seems related to the use of the evalin matlab's function. What is your version of matlab ?

Best, Stéphane.

it's Matlab 7.4.0.287 R2007a

I think that you need to CD to the directory where your file is:

cd C:\dynare\4.0.4\ejemplos
dynare example1

Best

Michel

Yes you're rigth. that was the problem!!

Gracias!!!!!!

I am sorry to re-open this subject, but I too obtained the error mentioned, and the "cd" method did not work for me (see below). I am using Matlab R2007a 7.4.0.287, under Windows7, with the "Windows 2000 compatibility" workaround to get Matlab to function. Any help to solve what is undoubtedly a simple error would be appreciated. Regards.

Hi,

There seems to be an problem with your installation of Dynare. Please check the following points:

1) Clean your MATLAB path, by removing any pointer to an old or current version of Dynare
2) Maybe reinstall Dynare 4.1.0, using the Windows installer on the website: it looks like you don't have all the MEX files (the one for "Sylvester equation" is missing)
3) Then run MATLAB, and type the following

Code: Select all

addpath D:\Quant\Dynare\Dynare_v4.1.0_23Dec2009\matlab
cd D:\Quant\Dynare\work
dynare lubikschorf2007.mod


In other words, you have to add Dynare "matlab" subdirectory to the path; and you need to first CD to the directory where your MOD file is, then run Dynare from there.

Hope that helps

Thank you very much! Following your suggestion, I have re-installed Dynare and now it works. (Curiously, for info, everything worked fine with Octave even before re-installation ...)
Regards

I am also sorry to raise the subject again, but I am experiencing somewhat similar problem. I can't open the .mod file and the error code in my case is 108

>> addpath c:\dynare\4.1.0\matlab
>> cd c:\dynare\4.1.0\matlab
>> Dynare minetest
Warning: Could not find an exact (case-sensitive) match for 'Dynare'.
c:\dynare\4.1.0\matlab\dynare.m is a case-insensitive match and will be used instead.
You can improve the performance of your code by using exact
name matches and we therefore recommend that you update your
usage accordingly. Alternatively, you can disable this warning using
warning('off','MATLAB:dispatcher:InexactMatch').

DYNARE: can't open minetest.mod

I am currently using Matlab2007a on Windows 7.

Anyone knows what might be the problem?

Thanks,

Why do you 'cd' to the 'matlab' subdirectory of Dynare?

This directory contains internal M-files, and should not contain your MOD file. In your case, it seems indeed that your MOD file is not there.

Suppose that your MOD-file is in c:\dynare\work\minitest.mod, you should type:

Code: Select all

addpath c:\dynare\4.1.0\matlab
cd c:\dynare\work
dynare minitest


thanks a lot Sébastien, now i see the problem.

dear,

When using Dynare the following error message appears:


addpath c:\dynare\4.1.1\matlab
cd c:\dynare\work\cours4

We also tried to re-install dynare 4.1.1;
I am using matlab R2007a 7.4.0 under windows7


Any help to solve would be very appreciated.

Best regards,

If you click on the error message, simul_olg.m opens and you see what's the problem. The preprocessor did not recognize your comments like

Code: Select all

// do "help log10" - log10 <> log

as comments.
You should delete these comments or move them to an own line and the code will run. Note that there is also a semicolon missing after

Code: Select all

load param_matrix

Thank you for your post !!but it doesn't change anything, i have always the same comments!!!

Then please post the param_matrix-file.
