These seem like basic programming questions, not MATPOWER questions. There are examples in the Getting Started section of the MATPOWER manual (second example in Section 2.3.2 in particular) that illustrate how to load a case, modify it and call runpf. If you need to run it 10 times, simply put it in a loop.
Also, the fact that this question is nearly identical to questions I’ve gotten from others (off-list) in the past few days prompts me to point you to FAQ #2. -- Ray Zimmerman Senior Research Associate B30 Warren Hall, Cornell University, Ithaca, NY 14853 phone: (607) 255-9645 On Feb 21, 2014, at 5:56 AM, ambi ka <rambi_2...@yahoo.co.in> wrote: > Sir, > I have doubt.
