I used to declare parameters values in the preamble of the .mod file using an external .m file, i.e.
parameters bet sig
[bet, sig] = calibr_parms
This syntax used to work with Dynare 3 but it does not work anymore with Dynare 4. I used this syntax because my parameters values come from a stores .csv file which is uploaded in the auxiliary file, using importdata() command.
Is there a way to to it with Dynare 4?
