mspec returns ZERO spp, snn #16

Closed hongandyan closed 3 years ago

hongandyan commented 3 years ago

I'm trying to use mspec as [f,spp,snn]=mspec(1,cv,[]); but the returned values are f=0, spp and snn are all zeros. My raw data is here https://www.dropbox.com/s/qj0zrrmw8usl88t/PaPa2.mat?dl=0 where cv = UU_obs + i*VV_obs; cv=cv-mean(cv);

Where could be wrong? thanks

The two most likely causes are (i) you put your data in as a row vector (it must be a column) or (ii) it contains a non-finite value. If neither of those work, let me know and I'll check out your data. Jonathan

Thanks for the quick help! Indeed it's a row vector causing the issue. After chanigng to column, it works like a charm. thanks again for your effort on this package. Hong
