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

[Rik]

Update of bug #65877 (group octave):

                Priority:              5 - Normal => 3 - Low                
              Item Group: Unexpected Error or Warning => Matlab Compatibility

Follow-up Comment #2:

Confirmed as well on development branch.  However this has easy workarounds
that are probably clearer code anyways.  I'm lowering the priority.  Because
Matlab does accept this construct, I'm changing the Group to "Matlab
Compatibility".

The issue is that the code '{:}' is asking the interpreter to look up the
variable value for 'A.a', but that variable doesn't exist.  One could, as
Matlab has done, check to see that this is an assignment to a non-existent
variable and thus suppress the error message and proceed with assignment. 
But, it is clearer to just assign a cell array to the desired variable.


A.a = {1};


That is clear as to intent.
