I am facing this kind of error

"Row 'eq1(14)' infeasible, all entries at implied bounds"

in a problem that a GAMS script gets data from MATLAB. I have seen some posts about conflict refiner (e.g., irreducible infeasible subset), but I really can not understand the way it is going to work what am I passing as an argument and whether I write this command in GAMS or in MATLAB and how exactly.

I've not worked with the GAMS/Matlab interface, but iis is a CPLEX option and not a GAMS option. So when you're in GAMS, you just need to put it in a cplex option file (i.e., cplex.opt that is by default put in the GAMS projdir folder). If you're calling a gms file from Matlab, you can create the option file as I described and add a model.optfile = 1; line to your GAMS code.
