摘要：
A comparative study of the performance of Davidson's method and the CG method was carried out using arbitrary symmetric matrices constructed by a simple program. The values of the quadratic function obtained by both methods were listed along with the number of iterations taken. Overall, the results obtained indicate that Davidson's method outperforms the CG method as a linear solver.
