[ncl-talk] Sub: EOF

[Dennis Shea]

Your questions are vague. You must be clear.
We don't have the time to determine what you mean.
Our time is valuable too!

As noted in the documentation, the sign of the EOF is **arbitrary**.

You previously asked for the data set used in

http://www.ncl.ucar.edu/Applications/eof.shtml
Example 2

NCL matches the result at  http://meteora.ucsd.edu/~pierce/eof/eofs.html

If another software tool has different signs for the patterns. No big deal.

The NCL examples include results/examples from text books. NCL matches them
exactly.

Really, if as you say,  "Results from ncl not consistent with results from
other programming language" , then please use the other languages.
