I added isequalwithequalnans as a legacy function here https://hg.savannah.gnu.org/hgweb/octave/rev/5bf1d8a0bcf7.

The function is still documented and does not produce a warning message if used:


The help mentions:

ISEQUALWITHEQUALNANS is not recommended. Use ISEQUALN instead.

Sure, can someone with a recent Matlab version (R2018a) that the function is still available and only produces a warning message if used?

If that is the case then we can make it a legacy function.

Following the discussion in bug #54417, should we reconsider having isequalwithequalnans available?

A better solution is to update to using isequaln (http://www.mathworks.com/help/matlab/ref/isequaln.html) which is the recommended replacement from Mathworks and is already available in Octave core.

As discussed in http://lists.gnu.org/archive/html/help-octave/2017-01/msg00149.html, isequalwithequalnans has been removed from Octave 4.2.0, and it is still available, albeit not recommended, in Matab R2016b.
VLfeat package http://www.vlfeat.org/ also use this function in
its testing, so I think that it should be returned to deprecated directory.
