Sums items from Src with matching corresponding indexes from Bins and places result in self.

Pascal
function GroupSumIteration(const Bins: TMtxVecInt; const Src: TMtxVec; const BinsMax: integer): TVec; overload;
Description

The size of self is checked to be BinsMax+1. The routine does not initialize the calling vector to 0. The routine does not perform additional range checking, because BinsMax is provided explicitely (memory overwrite is possible).
