Octave:
>> stdfilt (magic(5))
ans =
12.0876 10.4854 9.0108 8.6168 6.9901
10.5567 7.7460 7.8440 8.5310 7.0534

5.8949 7.6721 12.5100 11.0227 7.5829
After changing
values_fvec[se_ind] = in(in_sub) + heights_fvec[se_ind];
to
values_fvec[se_ind] = in(in_sub); // + heights_fvec[se_ind];
>> stdfilt (magic(5))
