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.
