Since fftw3 is part of the distribution, if it is installed you should
get the package version in response to the command "rpm -q fftw3". If
you want to see if your compilation of octave linked to it, try "ldd
`which octave` | grep fftw". If that does not give any results (meaning
it did not link), it is probably because fftw3-devel is not installed
(try "rpm -q fftw3-devel" to find out). I suspect it is unlikely that
atlas is installed, but you might try something like "locate libatlas"
to check for it.
