half-assed rcond

[Søren Hauberg]

Hi,
  For some time I've been using some written-for-matlab code that 
requires the 'rcond' function, which Octave doesn't have. For this I've 
been using the following half-assed implementation:

function rc = rcond(A)
  [dont_care, rc] = det(A);
endfunction

Just wondering if you wanted a documented, error-checking, etc., version 
of the above code, or if that implementation is too in-efficient?
