I just want to ask a general question about the message error

Warning: Matrix is close to singular or badly scaled.
Results may be inaccurate. RCOND = 9.966866e-017.

I have obtained this error message but after it I obtain the
STEADY-STATE RESULTS, the Residuals of the static equations( which are0),The rank condition is verified ;the MATRIX OF COVARIANCE OF EXOGENOUS SHOCKS,the
POLICY AND TRANSITION FUNCTIONS,the THEORETICAL MOMENTS,the variance decomposition and matrix of correlation. Can the result obtained be correct after this error message? thank you for answering me

Unless you have very good reasons to trust your results (so that the error message is just do to numerical accuracy such as extreme non-linearities), this is a bad sign. What does model_diagnostics say?

Dear Jpfeifer
concerninng the problem that I face with the oscillating IRF , I don’t find solution even without the budget constraint and changing the fiscal rule modelisation of government spending and taxe as well as the data .

I change the model .I now work with the one of (Gali and Monacelli ,2005; Monacelli ,2005 ; Justiniano and Preston,2010) with some modifications.
In fact I face this message :

Matrix is close to singular or badly scaled
.Results may be innacuuate

…Is it a bug ? should I change the version? I am working on 4.4.3
.please help me …this is my last code to finish my thesis… data6.m (13.1 KB) article2modif.mod (10.6 KB)
