Phase average of vector/scalar fields.

SF = phaseaverf(F,T), if T is a number, returns the phase average of 
vector/scalar fields F over a period T. 
If T is an integer, SF has length T, and is such that: 
  SF(i) = averf(F(i:T:end));   for all i between 1 and T 
If T is not an integer, then phaseaverf first performs a re-sampling of 
the data (linear interpolation). The result has length FLOOR(T). 
If T is an arbitrary vector, then performs a loop average of period 
T(end), starting from all values of T. 
  v = loadvec('*.vc7'); 
  sv = phaseaverf(v, 12);
