Re: Substitute all "i" and "j" with 1...4 in 4th polynomial function?

Sorr for my mistake... I am not math pro...

Your solution looks pretty obvious, but I still have only this:

I just cannot write that small comma between "i" and "j"

Thank you.

You need to use vector/matrix indices (matrix palette or by typing [), not literal ones.
