Hi,
The syntax using braces "will be" strictly equivalent to the ".entries" one.
Considering this, the example here do not actually work.
--> c = cell([2,1]);
-->c(1:2,1) = makecell([2,1], 'xx', 'yy')
c =
!"xx" !
! !
!"yy" !
-->v=list('u','v');
-->c(1:2,1).entries = v(:)
!--error 41
Incompatible output argument.
Even trying this in Octave gives an error :
octave:1> c(1:2,1)={'xx';'yy'}
c =
{
[1,1] = xx
[2,1] = yy
}
octave:2> v={'u','v'}
v =
{
[1,1] = u
[1,2] = v
}
octave:3> c{1:2,1}=v(:)
error: invalid assignment to cs-list outside multiple assignment.
error: assignment to cell array failed
error: assignment failed, or no method for `cell = cell'
octave:3> c{1:2,1}=v{:}
error: invalid assignment to cs-list outside multiple assignment.
error: assignment to cell array failed
error: assignment failed, or no method for `cell = sq_string'
So I guess we could raise the same error as before in this particular case.
