Dear Admin,
I found the the issue was a silly mistake of difference size
of array and now would like to withdraw this post. Is there a way to delete

Thanks a lot,
Both suggestions helped me and I could save it as below.
np.savez('eof_output',eof=eof1.data,pcs=pc1,lags=lags,lons=lons,lats=lats,x=x,y=y,clevs=clevs,eof_mask=eof1.mask)

Thank you very much for this tip.
Is there a typical way to save masked and the rest separately?. Not much
familiar with array handling in numpy.

np.savetxt can save it in a file and
there is no option like
write a string and then leave space and then write the array in above fashion.
I searched for a while but could not get any solution.

Hi all,
For a 3d array in matlab, I can do the below to reshape it before an
eof analysis. Is there a way to do the same using numpy? Please help.
[nlat,nlon,ntim ]=size(ssh);
tssh=reshape(ssh,nlat*nlon,ntim);
and afterwards
eofout=[]
eofout=reshape(eof1,nlat,nlon,ntime)
with best regards
