function [mpc]=MapBus(mpc,oldbusnum,newbusnum)
% Subroutine MapBus convert bus indices from oldbusnum to newbusnum. The
% conversion will be done to fields including buses, branches and
% generators.

%   [mpc]=MapBus(mpc,oldbusnum,newbusnum)
%
% INPUT DATA:
%   mpc - struct, input model in MATPOWER format
%   oldbusnum - 1*n array, the old bus indices which will be converted "from"
%   newbusnum - 1*n array, the new bus indices which will be converted "to"
%
% OUTPUT DATA:
%   mpc - sctruct, output model in MATPOWER format with converted bus
%         indices.
