[Nicholas Jankowski]

Update of bug #65221 (group octave):

                  Status:                   Fixed => In Progress            
             Open/Closed:                  Closed => Open

Follow-up Comment #3:

it seems that this fix runs into problems when movfun is called more if dim
changes to something that would fail the inputParser check the first time,
even if x was changed such that it should pass on the subsequent times.  E.g.,
calling movfun in the following fashion in the same session:


>> x = magic (4);
>> movfun(@mean, x, 2, 'dim', 1)
ans =

   16.0000    2.0000    3.0000   13.0000
   10.5000    6.5000    6.5000   10.5000
    7.0000    9.0000    8.0000   10.0000
    6.5000   10.5000   10.5000    6.5000

>> x = cat(3,x,x)
x =

ans(:,:,1) =

   16    2    3   13
    5   11   10    8
    9    7    6   12
    4   14   15    1

ans(:,:,2) =

   16    2    3   13
    5   11   10    8
    9    7    6   12
    4   14   15    1

>> movfun(@mean, x, 2, 'dim', 3)
error: movfun: failed validation of 'dim'.  Checked with "@(d) isempty (d) ||

ans(:,:,1) =

   16    2    3   13
    5   11   10    8
    9    7    6   12
    4   14   15    1

    9    7    6   12
    4   14   15    1

ans(:,:,2) =

   16    2    3   13
    5   11   10    8
    9    7    6   12
    4   14   15    1



it seems that this is too persistent. reopening report.
