This is a collection of small projects to start contributing to Octave. Projects of long duration are listed in the Projects page.
Info icon.svg
If you never contributed to Octave before, we suggest to start with our Developer FAQ.

Review and fix existing bugs

  • Review bugs that catch your interest on the Octave bug tracker on GNU Savannah.
    • A modern interface to the Octave bug tracker is given by SavannahAPI.
  • Discuss with the developers there how to fix that bug or upload a patch there.
  • Some bugs have already patches attached.
    • Help testing those patches.
    • Help updating outdated patches to the latest development version (this requires some Mercurial knowledge).

Implement missing Matlab functions

Use the Savannah patch tracker for submissions unrelated to an existing bug.

Write Built-In Self Tests (BISTs)

Writing BISTs improves Octave's regression testing and ensures that we don't break anything when we add new features.

Work on Octave packages

Easy Closes

Below is a non exhaustive list of bugs which should be looked at and appear to be easy Status (working from oldest stopped at 51317 aka items 1001-1050) Notes:

  • From this range ~5% could be closed
  • The last full scrub came from hardy for v4.2
  • Suspect many of the plotting and java bugs could be closed.
bug bug title status
#36954 datenum / datevec convert date-time string incorrectly during hour lost to DST siko1056 suggests closing as won't fix
#38297 [octave forge] (signal) bilinear not compatible with Matlab njank suggests this is resolved
#39243 patch {x,y,z,c}data properties are not independent hardy states original issue seems to be FIXED now
#39249 imread and 32 bit (float) TIFF images rik5 suggested closing
#40357 OOM when converting from sparse double to sparse logical hardy thinks this might be a DUPLICATE
#40739 Attempt to allocate (size_t)-1 bytes when trying to length-INT_MAX create sparse vector hardy states it might well be FIXED already.
#41661 [octave forge] (generate_html) generate_package_html page header contains wrong links cdf (OP) asks this item still relevant
#42118 COW memory issues when extracting small slices from large arrays rik5 isn't worth the maintenance burden
#42282 overloaded vertcat fails if some rows contain only built-in types cmb suggests this is a DUPLICATE
#42421 "find" function overflows for large sparse matrices appears issue is resolved
#43327 dir function is too slow siko1056 suggests to close as won't fix.
#43717 rats LEN Matlab incompatibility riks states wouldn't bother to fix this as Octave's solution seems better.
#44130 [octave forge] (statistics) mvncdf outputs different results for same input parameters mangosauce35 states not a bug but a matter of precision
#44971 [octave forge] (generate_html) fails to generate "See also" hyperlinks jbect questions if it is a DUPLICATE
#45166 [octave forge] (communications) typos in function docstrings appears can be closed
#45390 [octave forge] (communications) finddelay function appears can be closed
#45404 Breakpoints cannot be set in classdef methods or +package function files jwe suggest closing this
#45650 [octave forge] (communications) 'fmmod.m' help does not mention its last parameter (freqdev) appears can be closed
#45944 eig(X,'nobalance') does not exist in Octave vs. Matlab nir_krakauer shows this has been implemented
#46601 Command window problems on secondary portrait monitor rik5 suggest

likely to have been fixed.

#46640 [octave forge] (statistics) Can't install if io is not loaded lostbard asks if anyone still has this issue
#47496 Values in Workspace view are limited by 10 numbers mtmiller states let's just call this won't fix
#47553 textscan Whitespace characters different from Matlab lachlan states You're welcome to close it
#48088 document that issquare, iscolumn, isempty, etc operate on cell arrays pot states this is probably good enough
#48740 fieldnames(obj,'-full') OP states now this bug is fixed.
#49072 assigning double arrays to cell arrays: matlab incompatibility? mtmiller states may also be closed later as won't fix if no one reports any interest in working on this
#49091 MinGW std::acosh less accurate than Linux versions rik5 states

This and #48312 were supposed to be closed at the same time.

#49135 gnuplot: Default font must be set for "windows" terminal rik5 states was implemented on stable branch prior to 4.2 and the default after
#49275 history_append: new boolean option to mimic bash "histappend" option hardy states I think I will let it rest in peace.
#49360 odeset lacks documentation for solver options siko1056 on 28.09.2018 So maybe leave it open for another two years.
#50369 FLTK uimenu position inconsistent rik5 questions the bugs merit
#50502 [octave forge] (optim) nonlin_curvefit crash in 1.5.2 OP explicitly asks to close this bug
#60515 trace documentation jwe asks if there is anything to fix
#60652 Console becomes unusable after a few minutes of use OP never reported back
#60763 use of function 'properties' within a classdef appears to confuse parser jwe asks to close report

The equivalent suggestions for patches.

patch patch title status
#7537 Handle matlab way to store cell arrays in hdf5 files. nrjank states otherwise close bug as a 'won't fix'
#7825 built-in versions of base2dec and dec2base sebald states The fix is simple
#8046 [octave forge] (nan): ranks function - add support for multi-D arrays nrjank states patch likely can be closed.
#8369 [octave forge] (image): imresize - Change to imresize to reduce memory footprint fgnievinski suggests this is a duplicate of a bug and requests someone please close the present one.
#8666 doc: adjusting octave examples test to exactly match output siko1056 asks if anyone want to work on this otherwise we should close this item.
#8870 [octave forge] (odepkg) add metainfo.xml file for Gnome Software nrjank asks if this patch be closed
#9066 [octave forge] (communications) rcosfir: new function (deprecated but still present in Matlab) nir_krakauer states yes, it can be closed.
#9631 [octave forge] (benchmark) overhaul mtmiller considers dropping this patch
#9693 [octave forge] (signal) sos2ss: new function mtmiller states on 2018.09.26 feel free to ping or push if it gets to be the end of October
