Condition numbers and eigenvalues

Dear nmusers, could anybody provide me with references about condition numbers and eigenvalues? I already know how to calculate them and I'm especially interested in how to judge the results. Thanks and best regards, Kati ______________________________ Katharina Kuester Pharmacist, PhD student Freie Universitaet Berlin Institute of Pharmacy Dept.

Dear Katharina, Please see the best practices posting by Dr. Kowalski on nmusers, which contains some references: http://www.cognigencorp.com/nonmem/nm/99may012003.html http://www.cognigencorp.com/nonmem/nm/99may012003.html The second useful resource is Dr. Bonate's text-book (Pharmacokinetic-Pharmacodynamic Modeling And Simulation By Peter L. Bonate) where you can find a discussion around condition numbers on page 211. The simulation exercise described in the text-book is summarized in one of Dr. Bonate's posting at the following URL: http://www.cognigencorp.com/nonmem/nm/99oct022002.html http://www.cognigencorp.com/nonmem/nm/99oct022002.html Best wishes...MNS

Depending on your level of mathematics background, you might like to see a grassroots, theoretical explanation of eigenvalues, eigenvectors, condition numbers and how they relate in the realm of linear algebra. In this case I would suggest (among other books), Numerical Linear Algebra by Trefethen and Bau. http://web.comlab.ox.ac.uk/oucl/work/nick.trefethen/text.html Best, Mike Zager >>> "Katharina Küster" <[EMAIL PROTECTED]> 02/11/08 4:10 nm >>> Dear nmusers, could anybody provide me with references about condition numbers and eigenvalues?
