truncf
Truncate a vector/scalar field.

Description
TF = truncf(F) truncates the vector/scalar field(s) F to the largest 
centered square. 
 
TF = truncf(F,CUT) does the same, but eliminates bands of width CUT 
along the borders of the field (CUT is 0 by default). This is useful 
when boundary effects are expected, from bwfilterf for instance. 
 
If no output argument, the result is displayed by showvec or showscal.
