Request for ADIFOR 2.0 (windows version preferred)?
Hi, Everyone: I am now performing some academic studies related to ILDM ( a method to simplify detailed chemical reaction mechanism ). In this method, there is step concerned with the Schur Decomposition of the Jacobian matrix resulted from the right hand side of a set of ODEs, i.e. a matrix d(f1(x1,x2,...,xN),f2(x1,x2,...,xN),...,fN(x1,x2,...,xN),)/ d(x1,x2,...,xN). I hope you can send me a copy of ADIFOR (Win95/NT) by email if you have one. Other AutoDiff software cannot solve my problem very well (I heard from a very experienced Cornell visitor to our lab last week). Thank you! My email is yedong@gmail.com

Searching on adifor in google looks to me like it gets you right there. I generally suggest trying things like google first.

Pretty neat. It isn't a differential equation solver, but a generator of symbolic derivatives, taking Fortran 77 and input and generating Fortran 77 as output. Many differential equation solvers require functions to evaluate the derivatives. It is easy to find sites with google, including references and probably download sites for the paper. It seems to be free for noncommercial use, but a license is required. http://wwwunix.mcs.anl.gov/autodiff/AD_Tools/adifor.html  glen

Also check out GRESS. The URL is: http://www.autodiff.org/?module=Tools&tool=GRESS or http://wwwrsicc.ornl.gov/rsiccnew/cfdocs/qryAlphPackage.cfm?AlphBegin="G" (GRESS is about halfway down the page). Note that GRESS is NOT free. A license must be purchased from RSICC (Radiation Safety Information Computational Center), unless you work for someone (probably a government agency) who sponsors RSICC. GRESS was developed at Oak Ridge National Laboratory. ADIFOR was developed at Argonne National Laboratory and Rice University. Licensing is "free with restrictions".
