Go to /Applications/Utilities and double-click on the Terminal

At the prompt type "octave"

There will be little or no difference between Fink's "octave-atlas"  
and "octave" package. The plain "octave" variant uses Apple's  
optimized blas/lapack which produces a similar performance as compared  
to the atlas variant of blas/lapack.
