Re: findobj logicaloperator

[Felipe G. Nievinski]

Indeed, in Matlab I find:

>> findobj('-regexp','Type','image')

Warning: Regular _expression_ comparison is not supported for the 'Type' property: using ordinary

comparison. 

ans =

       471.01

>> findobj('-regexp','Type','image|surf|hggroup')

ans =

   Empty matrix: 0-by-1

I've filled bug reports with each MathWorks and Octave.

Thanks for replicating it.

-FGN.

For Octave, I see ...

figure
imagesc(rand(10))
oh = findobj('-regexp','Type','image|surf|hggroup')

oh = -284.82

oh = findobj('Type','image', '-or', 'Type','surf', '-or', 'Type','hggroup')

oh = [](0x1)

With Matlab, I see ...

figure
imagesc(rand(10))imagesc(rand(10))

oh = findobj('-regexp','Type','image|surf|hggroup')

oh =

   Empty matrix: 0-by-1

oh = findobj('Type','image', '-or', 'Type','surf', '-or', 'Type','hggroup')

oh =

    0.0107

It appears that there are bugs in both cases.  Please file a bug report for Octave at the link below.
