Didier Besset offered his great book "Object-Oriented Implementation of Numerical Methods An Introduction with Smalltalk and Java" to the community. We would like to thank Didier Besset for his great book and for his gift of the source and implementation to the community. You can find • Archive of the original book, with code in both Java and Smalltalk https://github.com/SquareBracketAssociates/ArchiveOONumericalMethods https://github.com/SquareBracketAssociates/ArchiveOONumericalMethods/blob/ma... • An abridged version of Didier’s book, without the Java implementation and reference; our goal is to make the book slimmer and easier to read. The implementation presented in this book is part of the SciSmalltalk library. https://github.com/SquareBracketAssociates/NumericalMethods https://github.com/SquareBracketAssociates/NumericalMethods/blob/master/2015... • SciSmalltalk library https://github.com/SergeStinckwich/SciSmalltalk. Both book versions are maintained by St ́ephane Ducasse and Serge Stinckwich. 27 Janvier 2015 -------------------------------------------- Stéphane Ducasse http://stephane.ducasse.free.fr http://www.synectique.eu / http://www.pharo.org 03 59 35 87 52 Assistant: Julie Jonas 03 59 57 78 50 03 59 35 86 16 S.
