(Orthogonal)Summator are notified via out-of-range matrixnr to omit contribution.

  • (Orthogonal)Summator uses ZeroInstance as default value and sets the value only when given matrixnr from lookup is within range.
  • this is preparatory for masking certain fragment results in the summation process.
  • Property mode set to 100644
