Syntax

Visual Basic (Declaration)
Public Overrides Function GetColumn ( _
	column As Integer, _
	startRow As Integer, _
	endRow As Integer, _
	rowStride As Integer _
) As Vector
C#
public override Vector GetColumn (
	int column,
	int startRow,
	int endRow,
	int rowStride
)
C++
public:
virtual Vector^ GetColumn (
	int column, 
	int startRow, 
	int endRow, 
	int rowStride
) override

Parameters

column (System.Int32)
The zero-based index of the column.
startRow (System.Int32)
The zero-based index of the row containing the first element in the column vector.
endRow (System.Int32)
The row index of the last element in the column vector.
rowStride (System.Int32)
The increment for the index in the column Vector corresponding to an increment of one in the new vector.

Return Value

A Vector.

Remarks

If the result is completely contained in the non-zero portion of the matrix, the return value is a GeneralVector. If the result is completely contained in the zero part, the return value is a ConstantVector. Otherwise, the return value is a BandVector.
