How do you multiply two arrays with a for loop?

I have two separate arrays, both 1 column. However, Array1 is 300 cells, while Array2 is 600000 cells. I want to iterate through both of these arrays simultaneously. For each element in Array1, I would like to multiply it by 2000 elements in Array2, saving the output.

Then the second element in Array1 would be multiplied by the next 2000 elements in Array2. And so forth.

I think you want something like

out = reshape(Array2,300,[]) .* Array1;

Then you can use reshape again to bring it back to one long vector if you need to.

If that does not do what you intend, perhaps you could provide example input and output for a small "toy" instance, for example where Array1 = 3x1 and Array2 = 6x1.
