  Octave 
 
    A  high-level  {interactive}  language  by  John 
  W.  Eaton,  with  help  from  many  others  like  {MATLAB},  primarily 
  intended  for  numerical  computations.  Octave  provides  a 
  convenient  {command  line  interface}  for  solving  linear  and 
  nonlinear  problems  numerically. 
 
  Octave  can  do  arithmetic  for  {real}  and  {complex}  {scalars} 
  and  {matrices},  solve  sets  of  nonlinear  algebraic  equations, 
  integrate  functions  over  finite  and  infinite  intervals,  and 
  integrate  systems  of  ordinary  differential  and 
  differential-algebraic  equations. 
 
  Octave  has  been  compiled  and  tested  with  {g++}  and  libg++  on  a 
  {SPARCstation  2}  running  {SunOS}  4.1.2,  an  {IBM}  {RS/6000} 
  running  {AIX}  3.2.5,  {DEC  Alpha}  systems  running  {OSF}/1  1.3 
  and  3.0,  a  {DECstation  5000}/240  running  {Ultrix}  4.2a,  and 
  {Intel  486}  systems  running  {Linux}.  It  should  work  on  most 
  other  {Unix}  systems  with  {g++}  and  libg++. 
 
  Octave  is  distributed  under  the  {GNU}  {General  Public 
  License}.  It  requires  {gnuplot},  a  {C++}  compiler  and 
  {Fortran}  compiler  or  {f2c}  translator.
