about the eofunc_Wrap

Dear everyone,

I'm now using eofunc_Wrap to do EOF analysis, according to the description of this function, I can use optEOF_at_jopt to determine whether covariance matrix or correlation matrix is used in eofunc_Wrap. However, it seems to me the results are exactly same from the two methods after I do it like the followings,

   optEOF = True
   optEOF_at_jopt = 1 ;correlation matrix
eof= eofunc_Wrap(x,neof,optEOF)

   optEOF = True
   optEOF_at_jopt = 0 ;covariance matrix
eof= eofunc_Wrap(x,neof,optEOF)

I don't know what happened, could anybody say anything about that? Thanks.
