Details:

This error: 
error: octave_base_value::array_value(): wrong type argument `complex matrix'
happens if I use "large" vectors in some signal processing code that I am
developing.  For short vectors, the code runs correctly. The back trace points
to line 40:

for K = 1:NT6;                  <=  line 40
  DC(K,1) = DT(K)*APC;
  APC = APC*DCK;
endfor;

(NT6 = 1020)

This is with the devel system as on 31 August.

summary:     Fix which() reporting incorrect directory for functions in
libinterp.

By large vectors, I mean length of about 1000.  Many of the vectors are
complex.  But, the above are all real.
If I use vectors of length around 100 there is no error
and results are correct.

By the way, as you can see, this code is very non-optimized.
It was "translated" from Fortran.  I am just starting on
optimizing it.
