*Improve logm, and sqrtm (see this thread: http://octave.1599824.n4.nabble.com/matrix-functions-td3137935.html) | *Improve logm, and sqrtm (see this thread: http://octave.1599824.n4.nabble.com/matrix-functions-td3137935.html) | ||
*Use pairwise addition in sum() to mitigate against numerical errors without substantial performance penalty (https://en.wikipedia.org/wiki/Pairwise_summation). | *Use pairwise or block addition in sum() to mitigate against numerical errors without substantial performance penalty (https://en.wikipedia.org/wiki/Pairwise_summation), see bug {{bug|61143}} for prior discussion. | ||
*Review implementing algorithm in this 2009 paper (https://epubs.siam.org/doi/pdf/10.1137/080738490) for xsum (sum with extra accuracy). The existing implementation uses a 2005 paper. | *Review implementing algorithm in this 2009 paper (https://epubs.siam.org/doi/pdf/10.1137/080738490) for xsum (sum with extra accuracy).

**Evaluate a line of code and return the output as a string (it would be best if it could provide three strings: output, warnings and errors). | **Evaluate a line of code and return the output as a string (it would be best if it could provide three strings: output, warnings and errors). | ||
**Query defined variables, i.e. get a list of currently defined variables. Bonus points if it could tell you if anything had changed since the last time you checked the variables (could also be done with signals). | **Query defined variables, i.e. get a list of currently defined variables.

*Allow side-by-side editing | |||
**Allow multiple Editor windows, so source files can be edited side-by-side within the GUI. | |||
**Add a vertical window splitter to the Editor so you can see the initialization code at the top while you type at the bottom. | |||
**Ensure that any particular file is only open in one tab at a time! | |||

* write {{codeline|xmlread}} and {{codeline|xmlwrite}}. This could be done using [http://xerces.apache.org/xerces-c/ Xerces C++ interface] which apparently is what [http://octave.1599824.n4.nabble.com/xml-in-octave-td4663034.html Matlab uses]. | * write {{codeline|xmlread}} and {{codeline|xmlwrite}}.
