public DenseVector<T> AddProductToVector(
	T alpha,
	Vector<T> vector,
	TransposeOperation trans,
	T beta,
	DenseVector<T> resultVector
)

Parameters

alpha  T
Multiplier for the vector-matrix product of this matrix with the vector vector.
vector  Vector<T>
A Vector<T>.
trans  TransposeOperation
A TransposeOperation value that specifies the operation, if any, to be performed on this instance before the multiplication.
beta  T
Multiplier for the vector resultVector.
resultVector  DenseVector<T>
The DenseVector<T> that is to contain the result of the multiplication.

Return Value

DenseVector<T>
The vector resultVector.

Remarks

The length of the vector vector must equal the number of columns in this instance. The length of the vector resultVector must equal the number of rows.

Exceptions

ArgumentNullExceptionvector is null.

-or-

resultVector is null.

DimensionMismatchExceptionThe length of the vector resultVector does not equal the number of columns of this matrix.

-or-

The length of the vector vector does not equal the number of rows of this matrix.
