shiftf
Shift the axis of a vector/scalar field.

Description
SF = shiftf(F) returns the same vector/scalar field(s) with the axis X 
and Y shifted, so that (X,Y)=(0,0) is in the left corner of the field 
(bottom-left corner when Y is upward, and top-left corner when Y is 
downward). 
 
SF = shiftf(F, OPT) does the same, specifying the new origin (0,0): 
      - 'center', 'c', 'middle' 
      - 'bottomleft', 'bl'       (by default) 
      - 'bottomright', 'br' 
      - 'topleft', 'tl' 
      - 'topright', 'tr' 
 
If no output argument, the result is displayed by showvec or showscal.
