DenseMatrix<T>.GetSubmatrixCore Method

Returns a sub-matrix of this matrix.

Definition

Namespace: Extreme.Mathematics.LinearAlgebra
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C#
protected override Matrix<T> GetSubmatrixCore(
	Slice rowSlice,
	Slice columnSlice,
	TransposeOperation transposeOperation,
	Intent intent
)

Parameters

rowSlice  Slice
A Slice structure that specifies the rows to return.
columnSlice  Slice
A Slice structure that specifies the columns to return.
transposeOperation  TransposeOperation
A TransposeOperation value that specifies whether or not this view should show the transpose of the matrix.
intent  Intent
An Intent value that specifies the intended use of the sub-matrix.

Return Value

Matrix<T>
A Matrix<T> that contains the specified rows and columns.

Remarks

The matrix returned by this method is a view on the original matrix. This means that any changes to the elements of the return value will cause the corresponding elements in the original matrix to change as well. Use the CloneData() or the ToDenseMatrix() method on the return value to create a matrix which has its own private element storage independent from the original matrix.

Exceptions

ArgumentOutOfRangeException

rowSlice does not define a valid slice of the rows of the matrix.

-or-

columnSlice does not define a valid slice of the columns of the matrix.
