What are the limitations of direct methods for solving a system of linear equations? How does Gauss Seidel method differ from Jacobi iteration? Solve the following system of linear equations using Jacobi iteration method:
What are the limitations of direct methods for solving a system of linear equations? How does Gauss Seidel method differ from Jacobi iteration? Solve the following system of linear equations using Jacobi iteration method:
$$ \begin{aligned} 2x - 7y - 10z &= -17 \ 5x + y + 3z &= 14 \ x + 10y + 9z &= 7 \end{aligned} $$

--- Direct methods (Gauss Elimination, LU Decomposition, Cramer's Rule) obtain the solution in a finite number of steps, but have limitations: 1. High computational cost: Gauss Elimination needs about $O(n^3)$ operations; expensive for large $n$. 2. Round-off error accumulation: Fixed long sequen...
