[Octave-bug-tracker] [bug #65877] struct field assignment using {:} produces invalid dimension error

[Nicholas Jankowski]

Update of bug #65877 (group octave):

                  Status:                    None => Confirmed              
                 Summary: struct field setting using semicolon => struct field
assignment using {:} produces invalid dimension error

Follow-up Comment #1:

can confirm with Octave 9.2.0. but i don't think the semicolon has anything to
do with it (or did you mean the colon).  Matlab is able to use that syntax for
object/field creation. Octave can only use that syntax for an existing
field/object:


>> A.a{:}=1
error: invalid dimension inquiry of a non-existent value

>> c = {99}
c =
{
  [1,1] = 99
}

>> A.a=c
A =

  scalar structure containing the fields:

    a =
    {
      [1,1] = 99
    }


>> A.a{:}=1
A =

  scalar structure containing the fields:

    a =
    {
      [1,1] = 1
    }


>> B.c = 1
B =

  scalar structure containing the fields:

    c = 1

>> B.a{:}=1
error: invalid dimension inquiry of a non-existent value

>> B.a(:)=2
B =

  scalar structure containing the fields:

    c = 1
    a = [](0x0)
