cell array indexing with logical index bug?

[Thorsten Meyer]

Hi,

with octave built from the current tip I get:


octave:1> a{1}=1
a =

{
  [1,1] =  1
}

octave:2> a(1)=[]
a = {}(1x0)
octave:3> a{1}=1
a =

{
  [1,1] =  1
}

octave:4> a(1==1)=[]
error: A(I): Index exceeds matrix dimension.
octave:4> a{1}=1;a{2}=2;
octave:5> a(1==1)=[]
a =

{
  [1,1] =  2
}
octave:6> a{1}=1;a{2}=2;
octave:7> a([1 2])=[]
error: A(I): Index exceeds matrix dimension.

So I can empty a cell array indexing with single index of type double, but not with a single index
of type logical. If the index is a vector, it does not matter if it is double or logical.

I am not sure if this is a bug. Imho, it is at least a misfeature: e.g., when I want to eliminate
entries of a by a certain criterion, i could do:
  idx = cellfun (@(x) x>0, a);
  a(idx) = [];
But with the above behaviour I have to specially treat the case that all elements of a fulfil the
criterion.

regards
