I have matrix A
A = [ 1 1 2 0.1;
2 2 3 0.02;
3 3 4 0.05;
4 4 5 0.3;
5 2 6 0.5;
6 2 7 0.4;
7 7 8 0.2;
8 3 9 0.9;
9 4 10 1.3
];
I want to add row values like that using a loop..
X1 = A(1,4)
X2 = A(1,4)+A(2,4)
X3 = A(1,4)+A(2,4)+A(3,4)
X4 = A(1,4)+A(2,4)+A(3,4)+A(4,4)
X5 = A(1,4)+A(2,4)+A(5,4)
X6 = A(1,4)+A(2,4)+A(6,4)
X7 = A(1,4)+A(2,4)+A(6,4)+A(7,4)
X8 = A(1,4)+A(2,4)+A(3,4)+A(8,4)
X9 = A(1,4)+A(2,4)+A(3,4)+A(4,4)+A(4,9)
B= [ X1;
X2;
X3;
X4;
X5;
X6;
X7;
X8;
X9;
];
How can I do that? Any tips?
Many Thanks in advance

None of your examples have A(:,2)=(A(:,3)+1) . In some cases A(:,2)=(A(:,3)-1) .
Your proposed rule is not clear on what to do when the relationship between those two columns does not hold.
