MRILDU: An Improvement to ILUT Based on Incomplete LDU Factorization and Dropping in Multiple Rows
We provide an improvement MRILDU to ILUT for general sparse linear systems in the paper. The improvement is based on the consideration that relatively large elements should be kept down as much as possible. To do so, two schemes are used. Firstly, incomplete LDU factorization is used instead of inc...
