	SymmetricMatrix<T>? result
)

Visual Basic

Public Shared Function OuterProductInto ( 
	matrix As Matrix(Of T),
	side As MatrixOperationSide,
	result As SymmetricMatrix(Of T)
) As SymmetricMatrix(Of T)

C++/CLI

public:
static SymmetricMatrix<T>^ OuterProductInto(
	Matrix<T>^ matrix, 
	MatrixOperationSide side, 
	SymmetricMatrix<T>^ result
)

static member OuterProductInto : 
        matrix : Matrix<'T> * 
        side : MatrixOperationSide * 
        result : SymmetricMatrix<'T> -> SymmetricMatrix<'T>

Parameters

matrix Matrix<T>: A Matrix<T>.
side MatrixOperationSide: Specifies whether the transposed matrix is the left or right operand.
result SymmetricMatrix<T>: The symmetric matrix that is to hold the result. May be null.

Return Value

SymmetricMatrix<T>
The new SymmetricMatrix<T>.

Remarks

This method uses the BLAS routine DSYRK.
