Details:

Hello, I'm working with a fiscal model in both matlab and octave (octave 3.8.1
and dynare version 4.4.3). My routine is to run a simulation file
(simula_mod_fiscal_04_bre_02b.m), where I set the value of parameters and
compute the steady state (calling mod_fiscal_04_ss_solve), prior to runing the
.mod file. The idea is to variate the nr_i parameter (it can be 0.2, 0.4, 0.6)
which stands for the proportion of non-ricardian agents (who work) in the
economy. When I run this simulation file on matlab, it works perfectly.
However, when running in octave, it doesn't "work" for nr_i = 0.2 and nr_i =
0.6 . I've checked the steady state values and they are equal for 0.4 but
different for 0.2. Does anyone know why this is happening? The files (.m and
.mod) are attached. 

Thank you!!!!

p.s: I believe the problem is in the fsolve() function (found in the
mod_fiscal_04d_ss_solve.m file)
