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.) ---

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. ---

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 ```auto command = [command ' ' varargin{i-1}]; ``` by ```auto command = '"' command '" ' varargin{i-1}]; ``` `'"'` is a double quote inside simple quotes `'" '` is a double quote and a space inside simple quotes Best Michel ---
