I have the following .mod file and when it runs in matlab i get the following message:

ans =

2

what does this mean????

It means you violated Matlab's naming convention. Function and variable names must start with a letter. 2 is not a valid name. Dynare outputs what you put in: 2

cheers. but now when I use an updated version the rank condition isn't verified.
