The section of code in the Gauss-Seidel method which calculates the new solution vector is seen below: for i=1:N x(i) = (b(i) - A(i,:)*x(:) A(i,i)*x(i))/A(i,i) endfor where N is the number of equations. Choose the correct edits if we wanted to use Jacobi method instead. Note: the variable named 'x_old' is the solution form the previous iteration Group of answer choices for i=1:N x(i) = (b(i) - A(i,:)*x_old(:) A(i,i)*x_old(i))/A(i,i) endfor for i=1:N x(i) = (b(i) - A(i,:)*x_old(:))/A(i,i) endfor for i=1:N x(i) = (b(i) - A(i,:)*x(:) A(i,i)*x(i))/A(i,i) - x_old(:) endfor for i=1:N sum = 0 for j=1:N if i != j sum = A(i,j)*x(j) endif endfor x(i) = (b(i) - sum)/A(i,i) endfor
