ideally I would like a solution that does not imply using VBA, but if that is the only way you know go ahead.
Does it exist any way of creating or emulating an array in excel that contains formulas instead of being static?
I know you can create a 1x2 array of constant values with ={10,20}. But what I need instead is to be able to create a 1x2 array of formulas something like ={10*A1,20*A2}. Actually the formula that I need to use in the array isn't a multiplication but a =Forecast.Linear(x,Ys,Xs).
It needs to be a 1x2 array because this part will be a parameter of another larger formula (another forecast.linear).
