Namespace: DigitalRune.Mathematics.Algebra
Assembly: DigitalRune.Mathematics (in DigitalRune.Mathematics.dll) Version: 1.14.0.0 (1.14.0.14427)

Syntax

C++

Copy

public MatrixF GetSubmatrix(
	int startRow,
	int endRow,
	int[] columns
)

Public Function GetSubmatrix ( 
	startRow As Integer,
	endRow As Integer,
	columns As Integer()
) As MatrixF

public:
MatrixF^ GetSubmatrix(
	int startRow, 
	int endRow, 
	array<int>^ columns
)

member GetSubmatrix : 
        startRow : int * 
        endRow : int * 
        columns : int[] -> MatrixF

Parameters

startRow: Type: SystemInt32
The index of the start row.
endRow: Type: SystemInt32
The index of the end row (included in the submatrix).
columns: Type: SystemInt32
The indices of the columns.

Return Value

Type: MatrixF
The extracted submatrix.

Exceptions

Exception	Condition
ArgumentOutOfRangeException	startRow is greater than endRow.
ArgumentOutOfRangeException	startRow or endRow is out of range.
IndexOutOfRangeException	An index in columns is invalid.

Remarks

The index array has to be interpreted like this: For example, columns[0] = 5 means that column 5 of this matrix will be copied into column 0 of the submatrix.
