scalar fields  COR = tempcorrf(F) computes the temporal
correlation function of the  vector or scalar fields F.  For a
scalar field w(t),     COR.f = < w (t) w(t+T) >,  where T is the
time lag, and <.> is the time average over t.  For a vector
field, COR.f is the sum of the correlation for each  component
of the vector (works with 2- and 3-component fields).  T takes
integer values between 0 and LENGTH(F)-1.  COR is a structure
which contains the following fields:    t:       time lag T
(integers between 0 and LENGTH(F)-1)    f:       correlation
function    unitf:   unit of correlation function    namef:
