Modular Filter Technique on Automatic Mesh Functions

This modular map technique is using the generally applications on automatic mesh procedures. I suppose, smilarly filter technique use the electrical engineering of signal filter models. I think, this function has attractive structure with mathematical modular arithmetic functions. This program or function has ?modularfilterpoints? is Random node values.

In the program algorithm is this selected the random nodes ordering for useful modular nodes as ?modularfilters? matrix.
