How to use Dynare in the Matlab?

Although the website write type ‘addpath c:\dynare\4.x.y\matlab, everytime I type the code in the command window in matlab, it appears the code ’ no such directory’.
Could someone help me?

That means you installed Dynare in a different directory. Or did you literally use 4.x.y? It must e.g. be 4.5.4 for version 4.5.4

I type 4.5.4.

Then check the path where you installed Dynare to.
