SenseClusters uses the package SVDPACKC to carry out Singular
Value Decomposition. There was a significant bug fix made in
las2.c (the SVD program we use) in February 2004, and it's very
important that you have this fix in your version of SVDPACKC.
If you look at the date/time on files in the distribution, they
should show Feb 18 2004 as the date of last update. In addition,
if you look in las2.c, you should find the following code:
if (*enough) {
/* bug fix supplied by Doug Rohde (MIT);
email contact: [EMAIL PROTECTED] (Feb 2004) */
mid = wptr[2];
wptr[2] = wptr[1];
wptr[1] = mid;
break;
}
If you have had SVDPACKC installed at your site for a long time (which
is possible, it's a popular package that has been around since 1993)
please check and make sure you are using the Feb 2004 version of better
that includes the above bug fix. If not, you can get a new version at:
http://www.netlib.org/svdpack/svdpackc.tgz
Please let us know if you have any questions or concerns!
Cordially,
Ted
