MRILDU: An Improvement to ILUT Based on Incomplete LDU Factorization and Dropping in Multiple Rows
2014
Journal of Applied Mathematics
Preserved Fulltext
We provide an improvement MRILDU to ILUT for general sparse linear systems in the paper. ...
And the dropping in multiple rows is more profitable, for there may be large differences between elements in different rows in each factor. ...
Perform incomplete LDU factorization for the matrix, compute multiple rows of factors and every time, and then apply dropping strategy to the obtained rows of and . ...
