4.6 Applying a stencil object

The syntax for applying a stencil is:

applyStencil(stencilname(),A,B,C...,F);

Where stencilname is the name of the stencil, and A,B,C,...,F are the arrays on which the stencil operates.

For examples, see examples/stencil.cpp and examples/stencil2.cpp.

Blitz++ interrogates the stencil object to find out how large its footprint is. It only applies the stencil over the region of the arrays where it won’t overrun the boundaries.
