Re: [ferret_users] @max and @min functions

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Sandip,
In Users' Guide Index under "Transformations" there are links to the general information about transformations and some examples.

The syntax is to list the transformations you want for each axis.  Here are a few more examples.  Try them out on your data-

var[x=@max,y=@max,z=@max,t=@max] ! @MAX transformation over the whole range of all axes

var[x=@max,y=@max,z=@max]  ! The maximum over X, Y, and Z for each time

var[x=300:330@max,y=0:40@max,Z=@max,T=@max]  ! Just a sub-range on some axes.

var[x=300:330@max,y=0:40@max,Z=@max,T=@AVE] ! The time average of the max over XYZ.

Dear all,
        I am not familiar with ferret. I want to find maximum and minimum values in 4D variable ( with I=1:4320, J=1:2160, K=1:70, L=1:12 ) . How should I use @min and @max functions for this? I will  also like to use @ngd and @nbd functions to get good and bad points.
       It will be really useful for me if someone can point to good references.


Thanks & Regards,
Sandip.
