Dear Commons-Math community, I've recently been using quite extensively the SYMMLQ linear iterative solver proposed by Page and Saunders, for its ability to handle symmetric *non-definite* systems. I know it's not the only one around, but that's not the point. My point is I would like to commit this implementation to the CM library. However, the core of the code is a mere port of the FORTRAN code downoadable on Pr. Saunders's homepage http://www.stanford.edu/group/SOL/software/symmlq.html. The FORTRAN source comes with a license, which I include here for the sake of completeness {quote} symmlq_f77.README
The software for SYMMLQ (f77 version) is provided by SOL, Stanford University under the terms of the OSI Common Public License (CPL): http://www.opensource.org/licenses/cpl1.0.php 11 Feb 2000: First set of files available for download from SOL. Please send comments to Michael Saunders, SOL, Stanford University saund...@stanford.edu 650-723-1875 ----------------------------------------------------------------------------- The f77 version of SYMMLQ involves the following files: symmlq.f symmlqblas.f (not needed if you have BLAS-1) symmlqtest.f {quote} My question is: how do I proceed from here? Is the CPL compatible with the Apache License (I think it is)? Courtesy would probably require to get in touch with Pr. Saunders. Do you allow me to do it on behalf of the CM community? Maybe one of the historical committers would rather do it? If Pr. Saunders agrees on signing the Commons License Agreement, would it still be required that the CPL be included? Thanks for your answers, Sébastien --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
