% @deftypefn {Function File} {[@var{m}, @var{v}] =} lognstat (@var{mu}, @var{sigma})
% Compute mean and variance of the lognormal distribution.
%
% @subheading Arguments
%
% @itemize @bullet
% @item
% @var{mu} is the first parameter of the lognormal distribution

% @item
% @var{sigma} is the second parameter of the lognormal distribution.
% @var{sigma} must be positive or zero
% @end itemize
% @var{mu} and @var{sigma} must be of common size or one of them must be
% scalar
%
% @subheading Return values
