## newbie question: assigment to N-d arrays returns strange values

```Hello,

```
This might be a known problem, but I couldn't find any reference to it. When assigning to an n-dimensional array (see below) I get results which are different from Matlab. Also, in one case I get some strange values in the array as well.
```
I wrote the the following code in Octave (using --traditional):

>>  m=zeros(3, 2, 2) ;
>>  a= [1 2 3 4] ;
>> m(3, :) = a
m =

ans(:,:,1) =

0        0
0        0
1        2

ans(:,:,2) =

0        0
0        0
0        0

```
which is not what I expected (3 and 4 were not assigned). Even worse, when I did
```
>> m=zeros(3, 2, 2) ;
>> a= [ 1; 2; 3; 4] ;
>> m(3, :) = a
m =

ans(:,:,1) =

0        0
0        0
1        2

ans(:,:,2) =

0.0e+00  *

NaN      NaN
NaN      Inf
NaN      Inf

```
This gives strange values on the 2nd "page". Further more, in normal mode the same code gave
```
octave:8> m=zeros(3, 2, 2) ;
octave:9> a= [ 1; 2; 3; 4] ;
octave:10> m(3, :) = a
m =

ans(:,:,1) =

0  0
0  0
1  2

ans(:,:,2) =

0.0000e+00   5.1715e-319
1.1116e-321    0.0000e+00
0.0000e+00    0.0000e+00

```
Is there a way to overcome this, or at least get an error/warning. I'm using octave-2.1.71
```
Thanks,

Amir.
