(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
**smoothf**(F,N,'0').
If no output argument, the result is displayed by showf.

**Example**
v = loadvec('*.vc7');
sf = **smoothf**(v, 5);
showf(sf);
