However, it seems that it does not call the default newtonpf.m function, which is supposed to compute the Jacobian matrix in the Newton-Raphson method. I even tested by deleting newtonpf.m from the directory, and runpf still ran without any issues, which confused me. According to the documentation, the default power flow algorithm used by runpf is newtonpf, so I expected the Jacobian matrix calculation to depend directly on this function. My questions are: Why does runpf keep running even without the newtonpf.m file? How is runpf computing the system Jacobian matrix in this case?
