Hi, nicrie.
Recently, I perform a svd analysis using nicrie / xmca code, the both shapes of left and right field matrixes were (time, lat, lon), and the value of time axis is (2000, 2001, ..., 2022).
I can get outputs of mca.eofs and mca.pcs, but I wonder that outputs were opposite compared with outputs of mca.expansionCoefs() of Yefee's xMCA.
Finally, I found that the same outputs can be obtained when time axis was reorded in inverse order, that is, (2022,2021,...,2000).
I want to know, which one is right? Is it a bug in code?
Thanks a lot.
