MATLAB: How to make loop and sum the result ?

Question

I have this loop…

for i=1:3

A=x((i-1)*3+1);

B=x((i-1)*3+2);

C=x((i-1)*3+3);

R=A^2+B^3+A*c;

end

i have constriants D=7 or <7

so i need this costraint=D-C-M

let say M=2

my equestion is how can i have the sumuation result of C from loop three times and then add this sum to constraint equation???

Thank you.

Answer 1

for i=1:3
A(i)=x((i-1)*3+1);
B(i)=x((i-1)*3+2);
C(i)=x((i-1)*3+3);
R(i)=A^2+B^3+A*c;
end
Summation=sum(C);
