New Post: denseSvd returns defferent results each time

Hi

I have a denseSvd from which I take the VT matrix as follows:

DenseSvd denseSvd = new DenseSvd(X, true);
Matrix<double> R = denseSvd.VT();

when I run my program twice on the same values I get different results. (Matrix R is different). Does anybody know why is that?
here are the results I get:

0   -0.124571344    -0.399180534    -0.304784305    -0.853629012    -0.059673442
0   -0.562896305    -0.198629699    -0.493132467    0.312634207 0.55024923

second time I run the program I get this result:

0   0.00639447  -0.007152342    0.087039515 0.739199858 0.667769157

any help would be much appriciated
Thanks
