Hello ! I was wondering if somebody could possibly help me. I am looking to create a vector of variables. [v1 v2 v3 v4 etc...] I dont want to assign the value to any of them. Then I want to multiply this vector by another, so the final answer will be: z=3v1 + 4v2 + 6v3 etc.... However, the amount of v1 v2 v3 can change each time the user runs the function. So i need the number of v's to be the number of rows in my other vector. I hope this is clear, and that somebody is able to help. Thank you !
