[Quantlib-users] question for MINPACK code under math/optimization

[QuantLib JS <qua...@gm...>]

Hello, QuantLib Community

Can someone please let me know the MINPACK source repo for:
https://github.com/lballabio/QuantLib/blob/master/ql/math/optimization/lmdif.hpp
https://github.com/lballabio/QuantLib/blob/master/ql/math/optimization/lmdif.cpp

We need test cases to find bug in our javascript version
<https://www.npmjs.com/package/minpack>

I googled around and found this: https://github.com/fortran-lang/minpack ,
it has test cases, but the `lmdif` function signature is different.

Thank you!
