Overload List

MultiplyAndAddAsLeftFactorCore(Double, Vector<Double>, Double, TransposeOperation, Vector<Double>, Vector<Double>) Multiplies the matrix with a vector, adds the scaled result to another scaled vector, and returns the result.
MultiplyAndAddAsLeftFactorCore(T, Matrix<T>, T, TransposeOperation, Matrix<T>, TransposeOperation, Matrix<T>) Adds the scaled product of two matrices to another matrix.

MultiplyAndAddAsLeftFactorCore(Double, Vector<Double>, Double, TransposeOperation, Vector<Double>, Vector<Double>)

Multiplies the matrix with a vector, adds the scaled result to another scaled vector, and returns the result.
C#
protected override Vector<double> MultiplyAndAddAsLeftFactorCore(
	double leftFactor,
	Vector<double> left,
	double productFactor,
	TransposeOperation transpose,
	Vector<double> rightFactor,
	Vector<double>? result
)

Parameters

leftFactor  Double
The scale factor for the vector.
left  Vector<Double>
The vector in the left term of the addition.
productFactor  Double
The scale factor for the product.
transpose  TransposeOperation
The transpose operation to perform on the linear operator before multiplying.
rightFactor  Vector<Double>
The right factor of the product.
result  Vector<Double>
The vector that is to hold the result. May be null.

Return Value

Vector<Double>
A vector that is the sum of leftFactor times left and productFactor times the product of this matrix and rightFactor.
