% @deftypefn {Function File} {} lognpdf (@var{x}, @var{mu}, @var{sigma})
% For each element of @var{x}, compute the probability density function
% (PDF) at @var{x} of the lognormal distribution with parameters
% @var{mu} and @var{sigma}. If a random variable follows this distribution,
% its logarithm is normally distributed with mean @var{mu}
% and standard deviation @var{sigma}.
%
% Default values are @var{mu} = 1, @var{sigma} = 1.
