Problem when using dynare 4

Dear all:
I am experiencing a problem solving a model with dynare 4

I am the junior user

I use non-linear equations ( even I use linear equations, it still have something wrong), and I get the following error message:

Configuring Dynare …
[mex] Generalized QZ.
[mex] Sylvester equation solution.
[mex] Kronecker products.
[mex] Sparse kronecker products.

Starting Dynare …

??? Error using ==> ss.inv

Do you have any suggestions about the causes of this error?
Thanks a lot

You didn’t declare Rss as a parameter



thank you.
