.oct file return a cell array, I want a regular array. Why?

[David Grohmann]

am attempting to write a .oct file that implements repmat in much faster 
c++ code. I have done this, but my oct file is returning a cell array 
instead of a normal multi dimensional array. 

I treat the source array as an ComplexNDArray and the result is an 
ComplexNDArray. But when it is returned to octave I get a cell array. 

my return statement is return octave_value(retval); where retval is an 
ComplexNDArray 

Any ideas? Thank you for any help you can provide.

octave:1> a = round(rand(3,3,3)*4)     
a =
ans(:,:,1) =
 1  2  3
 1  2  3
 2  1  4

ans(:,:,2) =
 3  1  1
 2  3  2
 0  0  1

ans(:,:,3) =
 3  1  4
 0  2  2
 0  2  2

octave:2> repmat(a,[1,2,3])        <<<<==== replaced repmat.m with my 
repmat.oct
ans = {3x6x9 Cell Array}


this should have produced a 3x6x9 non-cell array
