Hi dear there,
I am trying eof_4 example (http://www.ncl.ucar.edu/Applications/eof.shtml)
which focuses on computing EOFs; normalizing the principal components; and
projecting the anomalies via regression to compute the Antarctic
Oscillation (AAO). I downloaded the geopotential height data and placed it
in the directory I am working on.
However, it gives me the error messages below. I would highly appreciate
your help.
Warning! LAPACK routine returned eigenvalue <= 0.
Setting it to zero...

reference line.
