Zero parameter in ILU, ILU(0), means zero level of fill-ins in the coefficient matrix of the preconditioned system. You may consult the following book for details: Saad Y., Iterative Methods for Sparse Linear Systems, PWS Publ.Co., ISBN 0-534-94776-X regards DML

 July 1, 1999, 09:19 Re: GMRES/ILU(0): see Numerical Recipes #4 Patrick Godon Guest   Posts: n/a Why don't you have a look at Numerical Recipes, 1989, by Press, Flannery, Teukolsky and Vetterling, Cambridge University Press. This book has all the basic you want about solving equations on the computer. It has good references too and it is a good start indeed.
