Hello, I have the following two questions and I'd appreciate some clarifications:
1. What is the `neg_dSd_dVm` variable in newtonpf.m (at the top of the while loop, constructing the J part) do? With `runpf(case30)` it's a zero matrix, and I'm not sure physically what it is supposed to mean. 2. I'm in the process of porting some of the power flow code to another language (with a fair amount of change, but the main blocks e.g., in newtonpf.m were largely the same other than the syntax differences). I was hoping to put it on Github for people to use, and certainly for myself to use in my research later on. What would I need to include in my LICENSE file to acknowledge the contribution of Matpower, other than a copy of Matpower's LICENSE file from Github? Would I have to stick with the 3-clause BSD license? Thank you very much, Liangjie
