Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C# 
public override void BandSymmetricMultiplyAndAddInPlace(
	MatrixTriangle storedTriangle,
	int n,
	int k,
	double alpha,
	Array2D<double> a,
	ArraySlice<double> x,
	double beta,
	ArraySlice<double> y
)

Parameters

storedTriangle  MatrixTriangle
Specifies whether the matrix is an upper or lower triangular matrix.
n  Int32
The number of rows and columns in the matrix a.
k  Int32
The bandwidth of the matrix a.
alpha  Double
The scalar used to multiply the matrix-vector product.
a  Array2D<Double>
Reference to the first element in a one-dimensional array that contains the elements of the matrix.
x  ArraySlice<Double>
A reference to a one-dimensional array containing the elements of the vector x.
beta  Double
The scalar used to multiply y.
y  ArraySlice<Double>
A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.
