I guess the reason is this: In many of your 3-element rows there are more than 
one value meeting your condition. Example:

...
0.1 0.2 6
0.1 7 8
...

In the first row you get two values meeting your condition and the function 
"find" gives two entries with the same index i...

Try this after using find to eliminate the repeated i-entries: 

i = unique(i);
