2 cards from this section. Quick, good the night before a test.
Define the Gauss-Seidel method.
Consider how variables are updated in this method.
What does diagonal dominance imply?
Think about the structure of the matrix.
What is the primary advantage of the Gauss-Seidel method over others?
Think about how updates affect the convergence rate.
True or false: The Gauss-Seidel method is ineffective for diagonally dominant systems.
Remember the requirements for efficient convergence.
Apply the Gauss-Seidel method to solve the following system: 4x + y + 2z = 10, x + 3y + z = 12, 2x + y + 3z = 15. Assume initial guesses x=0, y=0, z=0. Show all iterations.
Keep updating based on the latest values you find!
You are given a matrix that is not diagonally dominant. Discuss whether you would choose the Gauss-Seidel method and why.
Consider the properties of the matrix and the behavior of the method.
