Jacobi method for symmetric 4× 4 matrices converges for every cyclic pivot strategy

E Begović Kovač, V Hari - Numerical algorithms, 2018 - Springer
The paper studies the global convergence of the Jacobi method for symmetric matrices of
size 4. We prove global convergence for all 720 cyclic pivot strategies. Precisely, we show …
