GenerateBCIRC

PURPOSE ^

Subroutine GenerateBCIRC is used to detect parallel lines and generate the circuit number of every

SYNOPSIS ^

function [BCIRC] = GenerateBCIRC(branch)

DESCRIPTION ^

 Subroutine GenerateBCIRC is used to detect parallel lines and generate the circuit number of every
 branch. 

   [BCIRC] = GenerateBCIRC(branch)

 INPUT DATA:
   branch: matrix, includes branch data in MATPOWER case format

 OUTPUT DATA:
   BCIRC: n*1 vector, includes branch circuit number

 NOTE: For one branch, if its circuit number is greater than 1 then it is
 parallel to one of the branch whose circuit number is 1.
