Details:
This idea came up on the help mailing list, just noting it as I think it would
be a useful enhancement. Note that it may end up being only corner cases, I'm
not sure what percentage of functions fall into this category.
The missing_function_hook function __unimplemented__ has a list of known
functions from Matlab and Matlab toolboxes, grouped by equivalent Octave
package name, so it can tell users which package to load or install to get a
given function.
This doesn't cover a couple cases: functions that *should* be in Octave core,
but are in a package (e.g. xmlread in the io package); and functions that are
in a package but are not in Matlab (e.g. assumptions in the symbolic
package).
The __unimplemented__ function could be enhanced to search through the list of
functions provided by installed packages, and show the user that a package
could be loaded to be able to use that function.
Example showing how to locate a given function in the pkg cache structure:
>> assumptions
error: 'assumptions' undefined near line 1 column 1
>> pkgs = pkg ("describe", "all");
>> pkgs{5}.name
ans = symbolic
>> any (strcmp (pkgs{5}.provides{1}.functions, "assumptions"))
ans = 1
