Log-normal to normal

Hi all,
lognpdf samples from a log-normal with mean m and variance v of the associated normal. however, is there a function that allows to pass the log-normal mean and variance to get log-normal probability densities, or alternatively a conversion function from log-normal mean and var to normal?
Thanks!

The documentation for lognpdf in the Description section has equations for mapping to and from the parameters for the lognormal distribution. You have to code them, but that doesn’t seem to be difficult.

Am I missing something, or isn't it simply mean() and var()? Just pass your log-normal generated samples into mean() and var() and it will give you the mean and variance of the log-normal data.
