Syntax

static bool GetIdenticalNodePairs
(
    const TArrayView< T > & InNodes,
    WeightFuncT InWeightFunc,
    TArray< TTuple< int, int >> & OutInvalidPairs
)

Remarks

Returns a list of integer pairs indicating which distinct pair of nodes have the same weight as a pair of the same node. These result in an ill-formed coefficient matrix which kills the interpolation. The user can then either simply remove one of the pairs and retry, or warn the user that they have an invalid setup.
