How can I reduce manually qz_zero_threshold

Dynare help (legacy posts)

Because I’m trying to solve for the steady state of the variables but one of the eigenvalues is close to 0/0, I have been looking in the board for a way to reduce the qz_zero_threshold, but cannot find one. Is this the same as TolFun in dynare_solve.m ? Because I also changed it, and it is not working.

See the manual on

qz_zero_threshold (dynare.org/manual/index_24.html#qz_005fzero_005fthreshold)

Note that this is often not a solution to the underlying problem as the singularity regularly comes from economic factors as opposed to pure numerical problems.
