(Temporal) smooth of a vector/scalar field.

SF = smoothf(F,N) returns the (temporal) smooth of the vector or scalar 
fields F (also called "Running average"), computed over N consecutive 
fields, using the function averf. The field number i is given by 
    SF(i) = averf(F(i:(i+N-1))); 
If the length of the input array F is L, the length of the smoothed 
array SF is L - 2*CEIL(N/2). (It is better to use an odd value for N). 
By default, smoothf considers that the zero elements of F are erroneous, 
and does not include them in the computations. If however you want to 
force the zero elements to be included in the computations, specify 
If no output argument, the result is displayed by showf. 
  v = loadvec('*.vc7'); 
  sf = smoothf(v, 5);
