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, 'nonzero') truncates the vector/scalar field(s) F to the 
smallest rectangular area excluding zero (erroneous or masked) 
elements. 
 
TF = truncf(F, CUT) eliminates bands of width CUT along the borders of 
the field (CUT is 0 by default). This is useful when boundary effects 
are expected (e.g., using bwfilterf). By default, CUT is specified in 
mesh units, unless the option 'phys' is specified (e.g., 
truncf(F, CUT, 'phys')). 
 
If no output argument, the result is displayed by showvec or showscal.
