I've just noticed:
octave:3> a=randn(1000);
octave:4> tic; svd(a); toc
Elapsed time is 2.7962 seconds.
octave:5> tic; [u,s,v] = svd(a); toc
Elapsed time is 25.3054 seconds.
Is this dramatic slowdown in second case expected,
or there is something wrong?
octave-3.2.4 on fedora linux / x86_64 / atlas 3.8.3
Dmitri.
