Hi all I have a short question relating to the usage of the summation sign in R.
Let's define A and B as two kxk matrice. My goal is to calculate the matrix C for the periods from 1 to 200 (n=1-200). C^(n) = Σ_(j=1)^n [(Σ_(i=1)^(j-1) A^i ) B (Σ_(i=1)^(j-1) A^i)’ ] How has that to be implemented in R (lets say for example for period = n = 150)? Thank you for your help!!
