Overload List

TriangularBandMatrixNorm(MatrixNorm, MatrixTriangle, MatrixDiagonal, Int32, Int32, ReadOnlySpan<T>, Int32)

Computes the norm of a triangular band matrix.
C#
public abstract T TriangularBandMatrixNorm(
	MatrixNorm norm,
	MatrixTriangle storedTriangle,
	MatrixDiagonal diag,
	int n,
	int k,
	ReadOnlySpan<T> 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.
diag  MatrixDiagonal
Specifies whether or not the matrix is unit triangular.
n  Int32
The number of rows and columns of the matrix.
k  Int32
The number of sub- or super-diagonals of the matrix.
ab  ReadOnlySpan<T>
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

T
The norm of the matrix.
