PHYS210: OCTAVE LAB 1
-------------------------------------------------------------------------

o Login and open a terminal window and a browser pointed to 
  these notes as usual 

o Create the subdirectory 'octave' in your homedirectory; we will be 
  using it extensively to copy/create octave code, though not today 

% cd
% mkdir octave

o Start octave from the commmand line --- note that there is NO 
  GUI for octave as we will be using it

% octave

o You should see the following

   octave:1> 

o Note the octave prompt 'octave:1>', which as was the case for the 
  shell (bash) or maple, means that octave is expecting input from 
  us.  Also note that '1' indicates that octave is waiting for our 
  first command, others will be numbered sequentially as we will see.

o For brevity (and for consistency with Gilat (Matlab text)), in the 
  remainder of the octave lab notes I will try to use 

  >>

  as the octave prompt


o Now follow along as we get acquainted with some basic usage of 
  octave by typing in expressions at the command line
