Overload List

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

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

Parameters

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

Return Value

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

MultiplyAndAddAsLeftFactorCore(T, Matrix<T>, T, TransposeOperation, Matrix<T>, TransposeOperation, Matrix<T>)

Adds the scaled product of two matrices to another matrix.
C# 
protected override Matrix<T> MultiplyAndAddAsLeftFactorCore(
	T factor,
	Matrix<T> left,
	T productFactor,
	TransposeOperation leftOperation,
	Matrix<T> rightFactor,
	TransposeOperation rightOperation,
	Matrix<T> result
)

Parameters

factor  T
 
left  Matrix<T>
The left operand of the addition.
productFactor  T
The scale factor for the matrix-matrix product.
leftOperation  TransposeOperation
The operation to be performed on this matrix before multiplying.
rightFactor  Matrix<T>
The right operand of the multiplication.
rightOperation  TransposeOperation
The operation to be performed on rightFactor before multiplying.
result  Matrix<T>
The matrix that is to hold the result. May be null.

Return Value

Matrix<T>
