Overload List

ExtractSymmetric(Int32, Int32, Int32, MatrixTriangle, Boolean)

Creates a SymmetricMatrix<T> from a part of a DenseMatrix<T>.
C# 
public override SymmetricMatrix<T> ExtractSymmetric(
	int dimension,
	int startRow,
	int startColumn,
	MatrixTriangle storedTriangle,
	bool reuseValuesArray
)

Parameters

dimension  Int32
The number of rows and columns of the new matrix.
startRow  Int32
The row in the matrix of the first element of the new matrix.
startColumn  Int32
The column in the matrix of the first element of the new matrix.
storedTriangle  MatrixTriangle
A MatrixTriangle value that indicates whether the elements of the symmetric matrix are stored in the upper or lower triangular portion of the block specified by startRow and startColumn.
reuseValuesArray  Boolean
A boolean value that indicates whether the storage array used by the matrix should be copied or reused for internal storage.

Return Value

SymmetricMatrix<T>
A SymmetricMatrix<T>.
