Explanation of this function

Hello Everyone,

I am trying to generate IRF for my data(Cholesky identification) and I have 6 variables, from 2008Q1 to 2021Q4. Can someone explain the meaning of these functions so I can alter the original code according to my need.

What do size(x,1) mean?

Thank you :)
