Re: please help me plot

David,

  Cygwin's Octave versions are outdated, and they would use
  GNUPLOT which gives enough headaches on XP/windows machines.
  On my vista machine with cygwin installed invoking octave
  itself used to be a training exercise, like waking your
  baby to go to school early morning.

  My suggestion is download version 3.0.1 (pretty stable)
  The newer ones are not stable though, they crashed with
  one of my filter design program. I am yet to report to
  octave-help on this. I am talking about 3.0.3.

  1. Remove Cygwin from winxp machine, unless u need it
     for some other reasons. Removing cygwin is also
     unclean and I used to delete the folder (barbaric act
     acc to windows OS).

  2. Download Octave3.0.1 from Octave-Forge.

  3. Install with jhandles as graphics backend. later you
     can always change to gnuplot if u dont like jhandles
     in octave environment.

  4. These are my personal experiences, which many people
     have all rights to agree/disagree. I am still facing
     issue with help command in Octave on Vista machine. So
     my take is if u are using linux then octave is for u,
     but if u are using windows try Scilab, their version 5
     is promising for signal and audio processing applications.
     though somewhat slow and no I/O provided for image/video
     processing, i suppose even octave does not do well on
     audio on windows, and aviread/aviwrite and movieplay
     functions are far fetched.

Regards
Bharat
