Namespace: Numerics.NET
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3

Overload List

ExtractTriangularBanded<T>(TriangularMatrix<T>, MatrixTriangle, Int32, MatrixDiagonal) Constructs a new upper or lower band matrix from the components of a triangular matrix.
ExtractTriangularBanded<T>(Matrix<T>, MatrixTriangle, Int32, MatrixDiagonal, Intent) Constructs a new upper or lower band matrix from the components of a triangular matrix.

ExtractTriangularBanded<T>(TriangularMatrix<T>, MatrixTriangle, Int32, MatrixDiagonal)

Constructs a new upper or lower band matrix from the components of a triangular matrix.
C# 
public static BandMatrix<T> ExtractTriangularBanded<T>(
	TriangularMatrix<T> matrix,
	MatrixTriangle storedTriangle,
	int bandwidth,
	MatrixDiagonal unitDiagonal
)

Parameters

matrix  TriangularMatrix<T>
The matrix that supplies the components.
storedTriangle  MatrixTriangle
A MatrixTriangle value that specifies whether to construct an upper or a lower triangular matrix.
bandwidth  Int32
The bandwidth of the BandMatrix<T>.
unitDiagonal  MatrixDiagonal
If true, the matrix is unit triangular. Only the elements below the diagonal in matrix are considered. If false, the diagonal elements of matrix are taken as the diagonal elements of the triangular matrix.

Type Parameters

T

Return Value

BandMatrix<T>
A BandMatrix<T> with the same components as matrix with lower and upper bandwidth equal to bandwidth.

ExtractTriangularBanded<T>(Matrix<T>, MatrixTriangle, Int32, MatrixDiagonal, Intent)

C# 
public static BandMatrix<T> ExtractTriangularBanded<T>(
	Matrix<T> matrix,
	MatrixTriangle storedTriangle,
	int bandwidth,
	MatrixDiagonal unitDiagonal,
	Intent intent
)

Parameters

matrix  Matrix<T>
The matrix that supplies the components.
storedTriangle  MatrixTriangle
A MatrixTriangle value that specifies whether to construct an upper or a lower triangular matrix.
bandwidth  Int32
The bandwidth of the BandMatrix<T>.
unitDiagonal  MatrixDiagonal
If true, the matrix is unit triangular. Only the elements below the diagonal in matrix are considered. If false, the diagonal elements of matrix are taken as the diagonal elements of the triangular matrix.
intent  Intent
An Intent value that specifies the intended use of the extracted BandMatrix<T>.

Type Parameters

T

Return Value

BandMatrix<T>
A BandMatrix<T> with the same components as matrix with upper and lower bandwidth equal to bandwidth.
