% @deftypefn {Function File} {} cauchy_inv (@var{x}, @var{lambda}, @var{sigma})
% For each element of @var{x}, compute the quantile (the inverse of the
% CDF) at @var{x} of the Cauchy distribution with location parameter
% @var{lambda} and scale parameter @var{sigma}. Default values are
% @var{lambda} = 0, @var{sigma} = 1.
