execute_adjoint

Parameters
source - it is either a FieldSet or a Field
target - it is either a FieldSet or a Field Note that formally in an adjoint operation of this type we should be setting the values in the target to zero. This is not done for efficiency reasons and because in most cases it is not necessary.
