AggregateInto(Matrix<T>, Vector<TResult>)

Note: This API is now obsolete.
Aggregates the columns of a matrix.
C#
[ObsoleteAttribute("Use the AggregateColumns method instead.")]
public Vector<TResult> AggregateInto(
	Matrix<T> values,
	Vector<TResult>? result
)

Parameters

values  Matrix<T>
The matrix whose columns to aggregate.
result  Vector<TResult>
The vector that is to hold the result. May be null.

Return Value

Vector<TResult>

AggregateInto(Vector<T>, IGrouping, Vector<TResult>)

Note: This API is now obsolete.
Groups the elements of a vector according to the specified grouping.
C#
[ObsoleteAttribute("Use the AggregateBy method instead.")]
public Vector<TResult> AggregateInto(
	Vector<T> values,
	IGrouping grouping,
	Vector<TResult>? result
)

Parameters

values  Vector<T>
The vector to aggregate.
grouping  IGrouping
A grouping.
result  Vector<TResult>
The vector that is to hold the result. May be null.

Return Value

Vector<TResult>

AggregateInto(Vector<T>, ReadOnlySpan<Int32>, Nullable<Boolean>, Vector<TResult>)

Note: This API is now obsolete.
Aggregates the elements of a vector according to the specified level indexes.
C#
[ObsoleteAttribute("Use the AggregateBy method instead.")]
public Vector<TResult> AggregateInto(
	Vector<T> values,
	ReadOnlySpan<int> levels,
	bool? skipMissingValues,
	Vector<TResult> result
)

Parameters

values  Vector<T>
The vector to aggregate.
levels  ReadOnlySpan<Int32>
An array of level indexes.
skipMissingValues  Nullable<Boolean>
Specifies whether missing values should be excluded from the aggregation. If null, then the value is inferred from values.
result  Vector<TResult>
The vector that is to hold the result. May be null.

Return Value

Vector<TResult>

AggregateInto<TPredicate>(Vector<T>, ReadOnlySpan<Int32>, TPredicate, Nullable<Boolean>, Vector<TResult>)

Note: This API is now obsolete.
Groups the elements of a vector according to the specified level indexes.
C#
[ObsoleteAttribute("Use the AggregateBy method instead.")]
public Vector<TResult> AggregateInto<TPredicate>(
	Vector<T> values,
	ReadOnlySpan<int> levels,
	TPredicate predicate,
	bool? skipMissingValues,
	Vector<TResult> result
)
where TPredicate : struct, new(), IFastFunc<T, bool>

Parameters

values  Vector<T>
The vector to aggregate.
levels  ReadOnlySpan<Int32>
An array of level indexes.
predicate  TPredicate
A predicate that filters the values that are to be included in the aggregation.
skipMissingValues  Nullable<Boolean>
Specifies whether missing values should be excluded from the aggregation. If null, then the value is inferred from values.
result  Vector<TResult>
The vector that is to hold the result. May be null.

Type Parameters

TPredicate
The type of predicate.

Return Value

Vector<TResult>

AggregateInto<TPredicate>(Int32, ReadOnlySpan<T>, Int32, ReadOnlySpan<Int32>, Int32, Int32, TPredicate, Boolean, SpanSlice<TResult>)

Groups the elements of a vector according to the specified level indexes.
C#
public virtual void AggregateInto<TPredicate>(
	int length,
	ReadOnlySpan<T> values,
	int stride,
	ReadOnlySpan<int> levels,
	int levelsStride,
	int maxLevel,
	TPredicate predicate,
	bool skipMissingValues,
	SpanSlice<TResult> result
)
where TPredicate : struct, new(), IFastFunc<T, bool>

Parameters

length  Int32
The number of elements in the input.
values  ReadOnlySpan<T>
A read-only span of values.
stride  Int32
The distance between successive elements in values.
levels  ReadOnlySpan<Int32>
An array of level indexes.
levelsStride  Int32
The distance between successive elements in levels.
maxLevel  Int32
The number of levels in levels.
predicate  TPredicate
A predicate that filters the values that are to be included in the aggregation.
skipMissingValues  Boolean
Optional. Specifies whether missing values should be excluded from the aggregation. The default is false.
result  SpanSlice<TResult>
The span that is to hold the result. May be null.

Type Parameters

TPredicate
The type of predicate.

Remarks

The elements of levels must be less than maxLevel. Negative values are considered missing and are not included in the aggregation.
