Hi all,

I’m working on a system of log-linear equations. As we know, steady state values of endogenous variable, (y_t-y)/y, is not needed in log-linear system, since they all zeros.

However, the coefficients of those linear equations usually depend on the steady state of the endogenous variables, y, not (y_t-y)/y. So I still need to compute the steady state values of y, except that y is declared as a parameter in .mod file.

My problem is that my equation system is too complicated and I couldn’ t solve for analytically y from that nonlinear equation system. So I wonder if it is possible to use fsolve in .m file, and name the file as FILENAME_steadystate.m…FILENAME_steadystate.m is typically used to compute the steady state of endogenous variable, (y_t-y)/y. Can it be used to compute the parameter, y?

BTW, one may question why I don’t solve y in an isolate .m file. The reason is that y depends on various parameters, which are undetermined yet since I want to estimate them with Bayesian method.

…Or, could the command`external_function (OPTIONS. . .);`

solve my problem?

Is there any examply I can refer to?
