Mon 28 Nov 2022 03:40:07 PM UTC, comment #4: ok, i spoke too soon. help sym.assume works help sym.char returns help for sym help sym.erf returns help for sym help logical.isAlways returns help for logical help @sym/assume works help ftp.ascii returns help for ftp so the behavior has changed, they no longer produce a not-found error. but it still isn't right. still wondering if it might make sense to consolidate the class help issues under a single report, or whether they should remain separate. see this bug bug #61521 bug #62804 (are there others?)	Nicholas Jankowski <nrjank>
Mon 28 Nov 2022 03:33:22 PM UTC, comment #3: testing a number of the suggestions in comments below, it seems most of what didn't work then, works now (tested in 7.3.0 with symbolic 3.0.0). with the package loaded, help sym.assume help sym.char help sym.erf help logical.isAlways help @sym/assume help ftp.ascii all return the expected help text. the comment #2 request for "help ftp/ascii" still fails. Is the primary concern of this bug now resolved? Is the comment #2 request is covered adequately by bug #61521 such that this can be closed?	Nicholas Jankowski <nrjank>
Wed 13 Mar 2019 08:16:55 PM UTC, comment #2: While you're at it, it would be nice to support "help ftp/ascii" for compatibility with Matlab, as documented here [1] for "help handle/delete". Another reason to support this is that Matlab docs often have "See Also: foo/bar" whereas we currently have to say "See Also: @foo/bar".

Tue 12 Mar 2019 08:26:39 AM UTC, comment #1: I see the same with the ftp class except they all seem to fail, even when there is not a built-in function with the same name: octave:1> help ftp.ascii error: help: 'ftp.ascii' not found I'll try to take a look since I have been making some changes related to looking up names/classes/packages/etc.	John W. Eaton <jwe>
Tue 12 Mar 2019 07:42:50 AM UTC, original submission: These examples come from the Symbolic package. "help sym.assume" works fine. But "help sym.char" does not. Nor does "help sym.erf". I guess the difference is there is no builtin "assume" but there are "char" and "erf" functions. > help sym.erf error: help: 'sym.erf' not found Notes: * "help @class/method" always works---this report is about the dot notation. * possibly related: if the class name is itself a builtin, the dot notation also fails, e.g., "help logical.isAlways". * Tested on 4.2 and 5.1.1. * 6.0.0 seems to have broken/removed "help @sym/assume" but this bug is present there too.
