"which" doesn't quite work ?

[Sergei Steshenko]

Hello,

the Email is inspired by a recent thread. Here is the screen session:

"
octave:1> Sample = {-0.123, 0.234}
Sample = 
{
  [1,1] = -0.12300
  [1,2] =  0.23400
}
octave:2> foo=Sample(1,2)
foo = 
{
  [1,1] =  0.23400
}
octave:3> help type
`type' is a function from the file 
/home/qemu/AFSWD/20120424/octave-3.6.2/share/octave/3.6.2/m/help/type.m

 -- Command:  type NAME ...
 -- Command:  type -q NAME ...
 -- Function File: dfns = type ("NAME", ...)
     Display the definition of each NAME that refers to a function.

     Normally also displays whether each NAME is user-defined or
     built-in; the `-q' option suppresses this behavior.

     If an output argument is requested nothing is displayed.  Instead,
     a cell array of strings is returned, where each element
     corresponds to the definition of each requested function.


Additional help for built-in functions and operators is
available in the on-line version of the manual.  Use the command
`doc <topic>' to search the manual index.

Help and information about Octave is also available on the WWW
at http://www.octave.org and via the address@hidden
mailing list.
octave:4> help which
`which' is a function from the file 
/home/qemu/AFSWD/20120424/octave-3.6.2/share/octave/3.6.2/m/help/which.m

 -- Command:  which name ...
     Display the type of each NAME.  If NAME is defined from a function
     file, the full name of the file is also displayed.

octave:5> type foo
foo is a variable

{
  [1,1] =  0.23400
}

octave:6> type Sample
Sample is a variable

{
  [1,1] = -0.12300
  [1,2] =  0.23400
}

octave:7> which foo, Sample
Sample = 
{
  [1,1] = -0.12300
  [1,2] =  0.23400
}
octave:8> which Sample, foo
foo = 
{
  [1,1] =  0.23400
}
octave:9> 
".

Please note that "help which" says "Display the type of each NAME", but both 
"which foo, Sample", "which Sample, foo" display the type of just _one_ last 
item, and not of each name.



Furthermore, in the same session:

"
octave:9> which "foo"
octave:10> which foo
octave:11> which Sample
octave:12> which "Sample"
",

i.e. if I specify just one name, nothing is displayed.

This is octave-3.6.2.

Is it supposed to be this way ?

Thanks,
  Sergei.
