[Octave-bug-tracker] [bug #52542] Weird behaviour of vertical concatenation with empty char array

[Rik]

Follow-up Comment #4, bug #52542 (project octave):

It is definitely the char() function call which is creating the problem.  I
can use string_fill_char() to set the fill character for the char()
constructor to another value.  This is then reflected in the output.


octave:2> string_fill_char ('X')
octave:3> double ([char(ones(0,4)); 'A'])
ans =

   65   88   88   88

octave:4> char (ans)
ans = AXXX


Offhand, it would seem that the constructor for char() is firing regardless of
whether the dimensions indicate that it should be an empty matrix.
