Definition

Namespace: Numerics.NET.LinearAlgebra.Implementation
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.2

Overload List

SymmetricBandMatrixNorm(MatrixNorm, MatrixTriangle, Int32, Int32, ReadOnlySpan<Complex<Double>>, Int32)

Computes the norm of a symmetric band matrix.
C# 
public override double SymmetricBandMatrixNorm(
	MatrixNorm norm,
	MatrixTriangle storedTriangle,
	int n,
	int k,
	ReadOnlySpan<Complex<double>> ab,
	int ldab
)

Parameters

norm  MatrixNorm
A MatrixNorm that specifies the type of norm to compute.
storedTriangle  MatrixTriangle
A MatrixTriangle value that specifies whether the matrix elements are stored in the upper or lower triangle.
n  Int32
The number of rows and columns of the matrix.
k  Int32
The number of sub- and super-diagonals of the matrix.
ab  ReadOnlySpan<Complex<Double>>
A span of T that contains the elements of the matrix in band storage format.
ldab  Int32
The leading dimension of the matrix ab.

Return Value

Double
The norm of the matrix.

Remarks

This method corresponds to the LAPACK routine ?LANSB.
