Operator splitting and error analysis in malaria modeling
作者：
Highlights：
• Operator splitting techniques have been applied to a non-homogeneous system of equations.
• The system has been split into three simpler operators depending upon the geometrical directions of the model.
• The sequential splitting scheme and the Strang-Marchuk splitting scheme are compared with the non-split reference solution.
• The order and accuracy of the methods have been derived analytically and by a numerical experiment for the test problem.
• The superiority of the splitting scheme over some non-split schemes in terms of computational time for a fixed global error has been established.
