GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab. It may also be used as a batch-oriented language.

Octave has extensive tools for solving common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations. It is easily extensible and customizable via user-defined functions written in Octave's own language, or using dynamically loaded modules written in C++, C, Fortran, or other languages.

LONI IBM p5 575s

To utilize this piece of software, utilize the SoftEnv tool. A user's ~/.soft file must contain the +octave-2.1.73 keyword. For example,

+gnu-4.1.1
+gdb-6.5
+ddd-3.3.11
+octave-2.1.73 #<- octave included here
@default

Once a user modifies their ~/.soft file, they must log out and login again.

To test that octave is in the PATH:

% which octave
/usr/local/packages/octave-2.1.73/bin/octave

To start octave in interactive mode,

% octave
GNU Octave, version 2.1.73 (powerpc-ibm-aix5.3.0.0).

Eric

Octave on Eric is available via SoftEnv using the same alias as for the LONI 575s above.

See Managing the Environment with SoftEnv for more information.

Porting From MatLab to Octave

Octave was created with MatLab compatibility in mind.
