the mpc.branch for this file is:
%% branch data
% fbus tbus r x b rateA rateB rateC ratio angle status angmin angmax
mpc.branch = [
1 2 0.00003120 0.00007487 0.00000000 999 999 999 0 0 1 -360 360
2 3 0.00003120 0.00007487 0.00000000 999 999 999 0 0 1 -360 360

YOu are giving negative or zero index to extract a element from matrix.
A = rand(10) ;
A(1,1) % no error
A(10) % no error
A(0) % error
A(-1) % error
A(0.5) % error
Read about MATLAB matri xindexing. Note that MATLAB indces start from 1 and they are positive integers
