Re: improvements in function kmeans.m

[oct]

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.
