Matrices before var representation in dynare v4

In order to estimate a medium sized DSGE model under learning, I need to obtain the matrices of coefficients of the linearised forward looking model, i.e:

This question has turned up before but was concerning Version 3. I believe that those matrices exist in dr1.m and are submatrices of jacobia_. However, I am unable to extract the necessary information from the m-file and jacobia does not appear anywhere in the workspace. Thus I am unsure how to obtain jacobia_, once I have run the mod file in Matlab.

I would be extremely grateful for some advice,

If you add the command line

at the end of the dr1.m file, the jacobian should appear in the workspace after you have run dynare.
