Overload List

AggregateColumns<U>(Aggregator<T, U>) Applies the specified aggregator to all the columns in the matrix.
AggregateColumns<U>(AggregatorGroup<U>) Applies the specified aggregator to all the columns in the matrix.
AggregateColumns<U>(AggregatorGroup<U>[]) Applies the specified aggregators to all the columns in the matrix.
AggregateColumns<U>(Func<Vector<T>, U>) Applies the specified aggregators to all the columns in the matrix.

AggregateColumns<U>(Aggregator<T, U>)

Applies the specified aggregator to all the columns in the matrix.
C# 
public Vector<U> AggregateColumns<U>(
	Aggregator<T, U> aggregator
)

Parameters

aggregator  Aggregator<T, U>
The aggregator to use.

Type Parameters

U
The type of the result of the aggregation.

Return Value

Vector<U>
A vector that contains the result of the aggregations indexed by the matrix's column index.

AggregateColumns<U>(AggregatorGroup<U>)

Applies the specified aggregator to all the columns in the matrix.
C# 
public Vector<U> AggregateColumns<U>(
	AggregatorGroup<U> aggregator
)

Parameters

aggregator  AggregatorGroup<U>
The aggregator to use.

Type Parameters

U
The type of the result of the aggregation.

Return Value

Vector<U>
A vector that contains the result of the aggregations indexed by the matrix's column index.

AggregateColumns<U>(AggregatorGroup<U>[])

Applies the specified aggregators to all the columns in the matrix.
C# 
public Matrix<U> AggregateColumns<U>(
	params AggregatorGroup<U>[] aggregators
)

Parameters

aggregators  AggregatorGroup<U>[]
One or more aggregators to use.

Type Parameters

U
The type of the result of the aggregation.

Return Value

Matrix<U>
A new matrix that contains the result of the aggregations with rows indexed by the names of the aggregators and columns indexed by the matrix's column index.

AggregateColumns<U>(Func<Vector<T>, U>)

Applies the specified aggregators to all the columns in the matrix.
C# 
public Vector<U> AggregateColumns<U>(

Parameters

aggregator  Func<Vector<T>, U>
A function that aggregates the elements of a vector into a value of type U.

Type Parameters

U
The type of the result of the aggregation.

Return Value

Vector<U>
A new matrix that contains the result of the aggregations with rows indexed by the names of the aggregators and columns indexed by the matrix's column index.
