Subject Re: [MATH] Ordinary differential equations - stiff solver
Date Sat, 16 Apr 2016 01:41:32 GMT
Hello Gilles,

the Java code I have from LSODA is from a C-Code translation, which was at
MIT license.

I would definitely offer the LSODA Java code I already have, to get things
started. Is anyone else interested in starting this project? How can we
start it?


Best,
Stefan
