Q: combining IRFs into subplotted figures & iterating?

I’ve tried dealing with this problem by reinstalling DYNARE4.40 exclusively in my personal computer under path C:, but with things unchanged. The error just displays as :

Undefined variable “irf1.” or class “irf1.y_epsilon_A”.

Error in plotting (line 37)
eval(‘irf1.’ var{1,jj},ending_cell{1,ii}]);

I am wondering whether things could be improved or fixed. I have no idea how to figure out the wrongs since I am also quite new to Matlab. So sorry that I have so many questions, yet I have to ask anyone has any idea?

Best,

GOODLUCK
