[Rock-dev] rock and octave - looking for contribution

[Alexander Duda]

I currently using octave to process rock log data on the fly and feed
them back to orocos tasks. But the interface is still a bit ugly and
slow. Therefore if some more people are interested in using octave to
process data on the fly we could spent some time to improve it.

What currently works:
########################################################
# octave m.file which is called via engine.mytest
########################################################
function result = mytest(data)
  %data has the same layout as the typelib type 
  figure(1);
  plot(data.beam);
  sleep(0.01);
  result = data;
endfunction

########################################################
# ruby start script  
#######################################################
require 'vizkit'
require 'orocos/log'
require 'octave'

engine = Octave::Engine.new
log = Orocos::Log::Replay.open(ARGV)

log.sonar_rear.BaseScan do |data|
  a = engine.mytest(to_octave(data))
  from_octave(data,a)
  data
end

Vizkit.control log
Vizkit.exec
