Hello, I hope you are doing well
Just a simple question, I have this short code which includes a loop:
syms Y3 GOD
for j=1:numel(Y3)
if j==1
GOD(j)=Y3(j);
else
GOD(j)=Y3(j)-sum(GOD);
end
end
I am very intuitive with matlab, and I am not so good in algebra, how can I write these lines of code as formula?
I know there are several ways to convert a formula to matlab code but not the other way around....
any suggestion is higly appreciated
Best

What are Y3 and GOD initially? You define as sybolic, but treat as an array.

syms Y3 [1 5]
syms GOD [1 5]
for j=1:numel(Y3)
if j==1
GOD(j)=Y3(j);
else
GOD(j)=Y3(j)-sum(GOD(1:j-1));
end
end
GOD.'
GOD2 = [Y3(1), Y3(2:end)-Y3(1:end-1)];
GOD2.'
So you can replace the loop with the formula I show in GOD2
