I am a new Dynare user

[ambudon]

Hi All,

I am using Matlab 7.1 and have some issues with running the example files. Can you please help me out ?

I have downloaded the example files and stored them in Matlab. The path is :

C:\Program Files\MATLAB71\work\dynare_v3\example

Matlab can not run the files with extension ".mod". It gives the message undefined variable " " or class " " .

Hence, I created a ".m" file (filename is neogrowth.m by typing what is given in "Practising Dynare" and saved it and tried to run it. But it does not work. It gives the following message:

??? Error: File: negrowth.m Line: 19 Column: 38
The expression to the left of the equals sign is not a valid target for an assignment.

Do you have any idea whats going wrong ?

How did you run these example files ?

Thanks in advance.

Thanks a lot for the suggestion.

But that does not work. Let me explain.

I have installed dynare_v3 in the 'work' folder in Matlab. Hence the path is

C:\Program Files\MATLAB71\work\dynare_v3

In dynare_v3, there are sub-folders containing the .mod files.

Suppose I want to implement example1.mod file, which is in 'examples' sub- folder.

I make C:\Program Files\MATLAB71\work\dynare_v3\examples my current directory. Since I am in the current directory, I need not specify the whole path.
Then I type dynare example1 or dynare example1.mod.

It gives me following message:

dynare example1
??? Error using ==> dynare
'C:\Program' is not recognized as an internal or external command,
operable program or batch file.

I have seen this question in the forum. but i think, the solution is not applicable in this case.

Whats going wrong ?

Thanks,

Let's try:
dynare example1.mod

So you have to add .mod at the end of the file name. (It's clearly in the manual, as Michel answered you, you're eyes somehow skipped it.)

[ambudon]

nop, i tried both of them..

same message...

[horvathar]

Have you done the "set path" thing?
It's in the manual too. It's OK that you set the current directory for "examples", but additionally you have to add the dynare_v3/matlab path in the file/set path menu.
If you have already done this, I've no other ideas.

[ambudon]

Yes, i have done that as well...

The problem is with the space in the directory name. There is a reason why we suggested to install Dynare directly under c: ...

It is possible to protect agains spaces in directory name by modifying dynare.m on line 15.
Replace

Code: Select all

  command = [command ' ' varargin{i-1}];


by

Code: Select all

  command = ['"' command '" ' varargin{i-1}];


Code: Select all

'"'

is a double quote inside simple quotes

Code: Select all

'" '

is a double quote and a space inside simple quotes

Best

Michel

yes, once i installed dynare in C, it worked.

sorry for the trouble.
