covcorm: Calculates a covariance or correlation matrix.
--- Prototype function covcorm ( x [*][*] : numeric, iopt [2] : integer) --- The 1st argument is prototyped as two-dimensions [*][*] Your data is three-dimensional so T2 = f->T2 dimT2 = dimsizes(T2) ntim = dimT2(0) ; 1096 ndom = dimT2(1) ; 4 nsta = dimT2(2) ; 6 t2 = T2(domain|:,station|:,time|:) ; reorder t2_2d = onedtond( ndtooned(t2), (/ndom*nsta, ntim/) ) r = covcorm( t2_2d, (/ 1, 1/) ) ; (24,24) r@long_name = "cross-correlation" ;r@units = "" print(r) On 8/30/11 11:07 AM, Estefanía Jiménez wrote: > Hi everyone!
