subaverf
Substract the spatial or ensemble average of a field

Description
FF = subaverf(F) substracts the spatial average from the vector/scalar 
field F. If F is an array of fields, subaverf(F) substracts the 
individual spatial average from each field. 
 
FF = subaverf(F,AXIS) substracts the spatial average (computed by 
spaverf), averaged over the direction AXIS, where AXIS='X', 'Y' or 
'XY'. Default is 'XY'. 
 
FF = subaverf(F,'e') substracts from each F the field averaged over all 
F, as computed from averf. The field substracted is an "ensemble" or 
"phase" or "temporal" average. 
 
If no output argument, the result is displayed by showvec or showscal. 
 
Example:  showvec(subaverf(loadset,'e'));
