I’m using Matlab 2022b and the dynare5.2. When I execute the example1.mod file, it’s not working. And it showed me that "dynare (line 281) evalin (‘base’, [fname ‘.driver’]. I have find many ways but it still can’t be solved. I really need some help to solve it.

What is the full error message?

Starting Dynare (version 5.0).

That’s the all error.

That is strange. Does you full file path include any non-standard characters that may throw off Matlab?

Sorry, I don’t quite understand what you mean. I add the Matlab file of Dynare to Matlab. The file path was copied. So I think it’s correct.

I meant the full path. In my case it would be

```
C:\dynare\5.2\examples\example1.mod
```

I just ran `example1.mod`

on my system without any problem. I am using `MATLAB 2022a`

with `Dynare 5.2`

. My path is

C:\dynare\5.2\examples

Can you go to the `Dynare`

folder on `C drive`

where you installed it and find the `examples`

folder? Inside you will have `example1.mod`

. Can you navigate to that folder from your `MATLAB`

(set that as your current `MATLAB`

folder) and then try running the file?

In the `+example1`

-subfolder, is there a file called `driver`

?

I just run the example1.mod, but it still doesn’t work.

The error is “The use of operators is invalid.”

How did you try to run it? It seems you tried to execute it as Matlab code.

I try to run it by using “dynare example1.mod”, but get the error

"（The name could not be resolved） ‘example1.driver’。

error dynare (line 281)

evalin(‘base’,[fname ‘.driver’]);"

Did you try running the file by typing in `MATLAB Command Window`

the following statement?

`dynare example1`

If this doesn’t work, maybe deleting the `example1.driver`

file and then trying to run `example1.mod`

might help.

I have worked out this problem! I share my resolution：

I created a working folder, works, outside of the matlab directory to place the mod files. Then in matlab

cd:\soft\ works

dynare bkk

succeeded!
