Hey Guys! Using dynare is of great convenience for there is no paper-and-pencil linearization of a model which is time-consuming. However, for a model relying on qualitative analysis, which means economic interpretation matters, a linearized model will give a good intuition beneath all the numerical methods. So, is there any computer algebra method I can utilize in Matlab to get a linearization form, I know the form may not be unique, without paper-and-pencil work? Thanks!

The Schmitt-Grohé/Uribe toolbox relies on Matlab’s symbolic math toolbox.

There is also Tom Holden’s Matlab toolbox I refer to in this [post](https://forum.dynare.org/t/extract-log-linearized-model-equations-from-dynare/16438/4).
