I have this 4th degree polynomial function:
and I want to write it this way:
you know, substitute all "i" and "j" with 1...4. I dont want to do it manualy 🙂
Can MathCad help me somehow?
Solved! Go to Solution.
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"
You need to use vector/matrix indices (matrix palette or by typing [), not literal ones.
