Methods

AggregateInto<T, TResult>(Vector<T>, Aggregator<T, TResult>, Vector<TResult>) Aggregates the specified vector over each group and returns the result.
AggregateInto<T1, T2, TResult>(Vector<T1>, Vector<T2>, BinaryAggregator<T1, T2, TResult>, Vector<TResult>) Aggregates the specified vector over each group and returns the result.
AggregateInto<T, TResult, TPredicate>(Vector<T>, Aggregator<T, TResult>, TPredicate, Nullable<Boolean>, Vector<TResult>) Aggregates the specified vector over each group and returns the result.
AggregateInto<T, TResult, TPredicate>(Aggregator<T, TResult>, Int32, ReadOnlySpanSlice<T>, TPredicate, Boolean, SpanSlice<TResult>) Aggregates the specified vector over each group and returns the result.
As<TKey> Returns the grouping as a strongly typed Grouping<TKey> of type TKey.
GetCounts Returns a histogram of the number of observations in each group.
GetIndexes Gets a sequence of indexes for the grouping.
