When you write to the Ferret Users List, address the email to ferret_users@xxxxxxxx. Give your email a subject line which describes the topic of your question.
The answer that people will give there to a question such as this, is to please start by reading some documentation. This is a fairly small group. They are very helpful but this is too general a question.
In the documentation I referred you to before, here is a specific link:
The commands starting with LET are equations.
This section will be helpful, defining variables using mathematical expressions:
Another place you can start is the tutorial scripts. From the Ferret command line, do this:
yes? go tutorialIt will run Ferret commands and draw plots. This will give you an idea of how Ferret commands work. Also try this one:
yes? go mathematics_demoNext try this one, watching for the part that starts with these comments:
! The horizontal equations of motion on the rotating earth show thatThat starts a set of commands where some constants and some equations are defined.
Finally, if you have colleagues who use Ferret, they may be your best first source for scripts that do the kinds of calculations you wish to do.
