Subtracts a value from the component at the specified location.

Namespace: Extreme.Mathematics.LinearAlgebra.Sparse
Assembly:   Extreme.Numerics (in Extreme.Numerics)
Version: 2.1.7017.0

Syntax

Visual Basic (Declaration)
Public Overridable Sub SubtractAt ( _
	row As Integer, _
	column As Integer, _
	value As Double _
)
C#
public virtual void SubtractAt (
	int row,
	int column,
	double value
)
Visual C++
public:
virtual void SubtractAt (
	int row, 
	int column, 
	double value
)

Parameters

row
System.Int32
The row of the component.
column
System.Int32
The column of the component.
value
System.Double
The value to be subtracted from the component.

Remarks

Looking up a component in a sparse matrix is a relatively expensive operation. It is therefore more efficient to get and set the value of a component in one function call that performs the lookup only once.
