octave3.0-headers 1:3.0.1-3ubuntu1 (i386 binary) in ubuntu intrepid

 Octave is a (mostly Matlab (R) compatible) high-level language, primarily
 intended for numerical computations. It provides a convenient command-line
 interface for solving linear and nonlinear problems numerically.
 .
 This packages provides the include files needed to compile and link
 user-supplied code with GNU Octave. If you only write interpreted .m files,
 you do not need this package.
 .
 The package is architecture-specific as it contains machine-dependent
 compiler switches in the mkoctfile script.
