Multiplication of NDArray in oct file

[babelproofreader]

I am trying to convert an m file to an oct file and part of the m file code
is:- 
   
for hh = 1 : nt       
bi_star = bi_star + A( : , : , hh ) * data( : , : , hh + 1 )' ;
end 

where both "A" and "data" are of NDArray type. I have tried to extract the
values from the NDArray by using something like

A.extract( 0 , 0 , num_dims-1 , num_dims-1 , hh ) ;

but get the error message "error: ‘class NDArray’ has no member named
‘extract’ " when compiling. The only other way I can think of doing this at
the moment is to put nested loops within the hh loop to loop over both "A"
and "data" to fill in intermediate calculation matrices and do the matrix
multiplications and additions using these intermediate matrices. However,
this seems to be a very long winded way of doing things. Is there a more
efficient way of accomplishing this?
