I am new to dynare and matlab and am trying to run a NKDSGE model with foreign exchange constraints and I found this error

Error in Foreign (line 269) MATLAB 5.0 MAT-file, Platform:MACI64, created on: Sat Oct 5 07:29:38 2013
Error in dynare (line 120) evalin('base',fname);

I don't know how to proceed and don't know what to do from here. Please help. I use macbook and am able to run my lecturers tute so am not sure if it's something to do with installation or it's just my mod file.

Please post the mod-file.

Hi jpfeifer,
I managed to work around the above problem and after I have worked around it and adjusted a few things in the model, I now have an error of "Matrix is singular to working precision". Please find below my mod file.
I always appreciate your assistance and time and hoping to get assisted.

before steady to see that there are two problematic equations that do not seem to be linear.

Hi,
I wrote the code you suggested before steady but the error still comes up. Is there anything else I can do?
Thanks
Bertha

You say your model is linear. In this case, all steady states are . But using 0 as the steady state, equations 9 and 10 do not solve. Consequently, there is a mistake in those equations (unless they are still linear and the constant part is not 0)

Thanks very much, I sorted it out.
