Description

Weighted occurrence counts; each weight is added to its integer bin.

Parameters
ParameterDescription
weightsFinite Double weights matching the 1D source shape.
minLengthMinimum output length, non-negative.
Returns

Double sum of weights per integer index.

Throws
  • ValueException for invalid source/weights or unaddressable bins.
