Help in vector multiplication!!

Hi, i try to make a multiplication bewtween a vector and a scalar. I need the result in another vector, but i can´t do that. I need some help.....
The multiplication is:

So, it looks like you want

outvector[1] = scalar*invector[1]
for i > 1
outvector = scalar*outvector[i-1]

in Vensim, you'd do this as:

Code: Select all

vec : (v1-v10)
vecNext : (v2-v10) -> vecPrev
vecPrev : (v1-v9) -> vecNext

outvector[v1] = scalar * invector[v1]
outvector[vecNext] = scalar * invector[vecPrev]

Thanks, but I can't understand completely. It is possible to get a small model with this?

It doesn't exactly replicate your numbers - I think your table is wrong.

This kind of operation (essentially an iteration within a subscript range) requires subscript mapping and equations for individual elements:
