Re: horizontal two-point correlations

Buongiorno

Perhaps I am misunderstanding the question?

     z(t,x) where t and x are 'named' dimensions of size nt, nx

     mxlag = 3
     ra = esacr(z, mxlag) ; ===> ra(nt,mxlag)
     rb = esacr(z(x|:,t|:), mxlag) ; ===> rb(nx,mxlag)

The latter uses NCL's dimension reordering
