Hi, I’m happy to give you permission to do this. You might also look at the latest stuff at
http://www4.ncsu.edu/~ctk/knl.html
which is still under development.

Dear Professor Kelley,
I have had a good experience using your Matlab nonlinear equation solvers in the past, especially NSOLI and BRSOLA, and I am missing them since I switched to using Julia instead of Matlab.
Would you be willing to allow me, and possibly other developers, to port your codes to Julia, specifically the NLsolve.jl package
https://github.com/JuliaNLSolvers/NLsolve.jl
? Given that your Matlab codes seem to have no license (?) we would need written permission from you.
The NLsolve.jl package is under MIT license, which I copy below fyi. We would of course fully credit the origin of the codes both in the documentation and source comments.
Looking forward to hearing from you. Sincerley,
