• Singular linear systems
• Saddle point problems
• Parameterized inexact Uzawa method
• Semi-convergence

Recently, Zhang and Wang studied the generalized parameterized inexact Uzawa methods (GPIU) for solving singular saddle point problems (Zhang and Wang, 2013 [22]). In this note, we continue to discuss the semi-convergence of GPIU for solving singular saddle point problems, and weaken some semi-convergent conditions.
