I tried a few times to open an account for creating a bug/patch ticket, but still I have not received the email from you for verifying the email address. In that case I send you the modification in the attached code along with a test-case. For the attached test-case the modified code runs x 120 faster, depending on the data-size. Thank you.

You should open a bug or patch report at the octave tracker [1]. Then,
to actually submit a patch, the possible ways are, in order of "ideality":

1. have a clone of the statistics package somewhere from where we can
import your changes;
2. attach a cset file with your changes [2] which we can import with hg;
3. attach a simple patch file;
4. attach your modified kmeans function file.

You should be able to submit a bug report without being logged in. did you try this? you can add your email address at the bottom under "mail notification CC" so that you get copied on all correspondence. Doing that and attaching this modified file and test case will be a good first start to getting the code incorporated into Octave.  You can let this list know if you have problems doing the anonymous submission.
