DEFUN_DLD (rcond, args,,"-*- texinfo -*-\n\ @deftypefn {Loadable Function} {@var{c} =} rcond (@var{A})\n\ Compute the 1-norm estimate of the reciprocal condition number as returned\n\ by @sc{lapack}. If the matrix is well-conditioned then @var{c} will be near\n\ 1 and if the matrix is poorly conditioned it will be close to zero.\n\ \n\ The matrix @var{A} must not be sparse. If the matrix is sparse then\n\ @code{condest (@var{A})} or @code{rcond (full (@var{A}))} should be used\n\ instead.\n\ @seealso{cond, condest}\n\ @end deftypefn")
