Overload List

SubtractOuterProduct(Matrix<T>, MatrixOperationSide) Updates a Hermitian matrix by subtracting the product of a matrix and its transpose.
SubtractOuterProduct(Vector<T>, MatrixOperationSide) Updates a Hermitian matrix with the outer product of a vector and its transpose.

SubtractOuterProduct(Matrix<T>, MatrixOperationSide)

Updates a Hermitian matrix by subtracting the product of a matrix and its transpose.
C# 
public HermitianMatrix<T> SubtractOuterProduct(
	Matrix<T> matrix,
	MatrixOperationSide side = MatrixOperationSide.Right
)

Parameters

matrix  Matrix<T>
A Matrix<T>.
side  MatrixOperationSide  (Optional)
