Short projects

This is a collection of small projects to start contributing to Octave. Projects of long duration are listed in the Projects page.

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  • Help updating outdated patches to the latest development version (this requires some Mercurial knowledge).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.

• BIST for C++ functions
• BIST for m-files. See also Projects#Tests.

Work on Octave packages

• Take a look at https://gnu-octave.github.io/packages/ if you would like to work on some package there.

Easy Closes

bug	bug title	status
#32839	pkg build/install does not work with directories	OP states to close
#36954	datenum / datevec convert date-time string incorrectly during hour lost to DST	siko1056 suggests closing as won't fix
#38134	[octave forge] (signal) bug in remez	njank recommends closing
#38297	[octave forge] (signal) bilinear not compatible with Matlab	rjank 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.
#41011	scalar indexed assignment should cast input type	appears to give same results as ML
#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
