Dear Sir,
1) How to run CPF for any bus system?say 30 bus,14 bus,59 bus etc.
2) In MATPOWER cpf_test gives cpf for 30 bus system.In a post you have sent the 
test_cpf_14bus for 14 bus system.But it is giving error at line 12 as " wrong 
or incomplete ststement".Please clarify.
3) how to present the data for running cpf in MATPOWER?Data format?
4)How to change the parameters like loading parameter etc.for cpf in MATPOWER?
Thanks
