- The aggregator to apply to each group.
Type Parameters
- TResult
- The type of the result of the aggregator.
Return Value
Matrix<TResult>A new matrix, with rows indexed by the index associated with grouping, and as values the result of applying aggregator to each group of each column.
AggregateColumnsBy<K, TResult>(IList<K>, AggregatorGroup<TResult>)
Returns a new matrix that aggregates the columns grouped by the specified vector.
public Matrix<TResult> AggregateColumnsBy<K, TResult>(
IList<K> groupingVector,
AggregatorGroup<TResult> aggregator
)
Parameters
- groupingVector IList<K>
- The vector that contains the group memberships.
- aggregator AggregatorGroup<TResult>
- The aggregator to apply to each group.
Type Parameters
