  Hi!  
  I came across an incorrect expression for the sync() function:  


octave:55> sinc(-1:0.20:1-0.20)
   3.8982e-17   2.3387e-01   5.0455e-01   7.5683e-01   9.3549e-01          NaN
  9.3549e-01   7.5683e-01   5.0455e-01   2.3387e-01


Reproduced for Octave 7.3.0 and 8.2.0 Releases.

  Thanks
