Many people have already contributed to Octave's development. In addition to John W. Eaton, the following people have helped write parts of Octave or helped out in various other ways.

• Thomas Baier [email protected] wrote the original versions of popen, pclose, execute, sync_system, and async_system.
• David Bateman [email protected] improved the sort and min/max functions, made many functions N-d aware, converted several built-in functions to use Lapack instead of Linpack, split the functionality of load-save.cc out into the octave_value classes, and has contributed in many other ways.
• Karl Berry [email protected] wrote the kpathsea library that allows Octave to recursively search directory paths for function and script files.
• Georg Beyerle [email protected] contributed code to save values in Matlab's .mat-file format, and has provided many useful bug reports and suggestions.
• John Campbell [email protected] wrote most of the file and C-style input and output functions.
• Dirk Eddelbuettel [email protected] made Octave easy to install for users of Debian GNU/Linux.
• Brian Fox [email protected] wrote the readline library used for command history editing, and the portion of this manual that documents it.
• Klaus Gebhardt [email protected] ported Octave to OS/2.
• Kai Habel [email protected] implemted functions for performing coordinate transformations.
• A. Scottedward Hodel [email protected] contributed a number of functions including expm, qzval, qzhess, syl, lyap, and balance.
• Kurt Hornik [email protected] provided the corrcoef, cov, fftconv, fftfilt, gcd, lcd, kurtosis, null, orth, poly, polyfit, roots, and skewness functions, supplied documentation for these and numerous other functions, rewrote the Emacs mode for editing Octave code and provided its documentation, and has helped tremendously with testing. He has also been a constant source of new ideas for improving Octave.
• Cai Jianming [email protected] contributed the inital cell array implementation.
• Phil Johnson [email protected] has helped to make Linux releases available.
• Steven G. Johnson [email protected] added support for ATLAS, saving data in HDF5 files, and ported Octave's configure script to Autoconf 2.50.
• Mumit Khan [email protected] helped make it possible for Octave to be compiled by ISO standard C++ compilers other than GCC.
• Paul Kienzle [email protected] has provided many enhancements to improve Octave's compatibility with Matlab, and also maintains the collection of conributed code at http://octave.sf.net.
• Bill Lash [email protected] provided the unwrap function.
• Dirk Laurie [email protected] rewrote invhilb to be faster and more accurate.
• Friedrich Leisch [email protected] provided the mahalanobis function.
• Ken Neighbors [email protected] has provided many useful bug reports and comments on Matlab compatibility.
• Rick Niles [email protected] rewrote Octave's plotting functions to add line styles and the ability to specify an unlimited number of lines in a single call. He also continues to track down odd incompatibilities and bugs.
• Mark Odegard [email protected] provided the initial implementation of fread, fwrite, feof, and ferror.
• Gabriele Pannocchia [email protected] provided the dkalman.m function, added support for singular system matrices to dlqe and dlqr, and has made various other improvements to the control system functions.
• Tony Richardson [email protected] wrote Octave's image processing functions as well as most of the original polynomial functions.
• Petter Risholm [email protected] helped to implement much of Octave's N-d array functionality.
• Ben Sapp [email protected] implemented the debugger functions and added Texinfo markup commands to the internal doc strings.
• R. Bruce Tenison [email protected] wrote the hess and schur functions.
• Teresa Twaroch [email protected] provided the functions gls and ols.
• James R. Van Zandt [email protected] added support for reading and writing Matlab version 5 binary data files.
• Andreas Weingessel [email protected] wrote the audio functions lin2mu, loadaudio, mu2lin, playaudio, record, saveaudio, and setaudio.
• Fook Fah Yap [email protected] provided the fft and ifft functions and valuable bug reports for early versions.
