It's OK when I remove the gencost matrix from this case.
Thanks very much.
The interesting point is that with Matpower 3.2 there's no such problem even
though the number of gencost is inconsistent with the number of generators.
Best regards,

Your case file has 1165 generators, but only 3 generator costs. You need to
either remove the gencost matrix or update it to be consistent with the gen
matrix.

Dear all,
When I use matpower4.0b4 to calculate the power flow of a large-scale
power
system (the studied case is attached FYI) and save the results in a
specified file, a bunch of error messages occur:
%======================================
runpf('caseS1',mpoption,'caseS1_sol_NR.m')
??? Error using ==> subsref
Index exceeds matrix dimensions.
Error in ==> get_reorder at 50
B = subsref(A, s);

mpc.(field) = ext2int(mpc, mpc.(field), ordering, dim);
Error in ==> ext2int at 291
mpc = ext2int(mpc, 'gencost', ordering);
Error in ==> runpf at 131
mpc = ext2int(mpc);
%======================================
There are no problems when I do the tests with other cases.
Besides, if I run the same case with the same command on the platform of
matpower3.2, everything is OK.
I would be greatly appreciated if anyone can help me get over this.
