[Octave-bug-tracker] [bug #50282] CS-list example in documentation doesn't output stated output

[Martin Castillo]

Follow-up Comment #4, bug #50282 (project octave):

I tried doctest on doc/interpreter/
the result is in doctest.log.
if you look there, you'll see a lot problems. and many seem to be  the way
things are tested. for example:
rounding errors

 >> (-1) ^ (1 / 3)

      expected:  0.50000 - 0.86603i

      got     : ans =  0.50000 + 0.86603i


tests for wrong type(?)

   >> prod ([true, true], "native")

      expected:     true

      got     : ans = 1


testing strings (?) instead values.

   >> min ([-1 i 1 -i])

      expected:      -i

      got     : ans = -0 - 1i


I don't know what happened here...

  >> w =  1  3  3  6  6  6
    iw = 1  2  2  4  4  4
    

      expected: 
      got     : ??? parse error:

  syntax error

>>> w =  1  3  3  6  6  6
    iw = 1  2  2  4  4  4
    
            ^


Oh man:

   >> chop (-pi, 5, 5)

      expected:     -3.14150000000000

      got     : ans = -3.1415


   >> [ 1/0 e^800 ]

      expected:  Inf   Inf

      got     : warning: division by zero
ans =

   Inf   Inf


my favourite(before 'doctest .' I typed 'doctest'):

   >> disp (1)
    disp (2)
    run_history -1 -2

      expected: 
 2
 1

      got     :  1
 2
'doctest' is a function from the file
/home/mcd/octave/doctest-0.5.0/doctest.m

 -- doctest TARGET
 -- doctest TARGET -nonrecursive
 -- SUCCESS = doctest (TARGET, …)
 -- [NUMPASS, NUMTESTS, SUMMARY] = doctest (…)
     Run examples embedded in documentation.

     Doctest finds and runs code found in TARGET, which can be a:
        • function;
        • class;
        • Texinfo file;
        • directory/folder (pass ‘-nonrecursive’ to skip subfolders);
[...]



and while running, I got a bunch of the following:
