Re: [ferret_users] [FERRET]calculate spatial correlation of 2 variables

Hi Zhen,
The variance script defines a variable (not a function) called CORREL 
from the input variables that you define.  To see the whole script, type

yes? go/help variance

You'll see that at the end, there is a variable called CORREL defined 
and another called COVAR.  So, once you have run the script, you can 
just say

yes? list correl
yes? list covar

I'll see what we can do to add more information to the documentation to 
make this clearer.
