Abstract: In this paper, we consider the convergence analysis of the randomized double block Kaczmarz method and improve the upper bound of the error estimate in expectation of the randomized double block Kaczmarz method. Numerical experiments are given to demonstrate the theoretical results and to show a large gap between the new and the old bound.
