BlasLevel1..::..Ddot Method

BlasLevel1 Class See Also 
Returns the inner product of two vectors.

Namespace: Extreme.Mathematics.LinearAlgebra.Providers
Assembly: Extreme.Numerics.Net40 (in Extreme.Numerics.Net40.dll) Version: 4.2.11333.0 (4.2.12253.0)

Syntax

C# 
                      public abstract double Ddot(
	int n,
	double[] x,
	int xOffset,
	int incx,
	double[] y,
	int yOffset,
	int incy
)
Visual Basic (Declaration) 
                      Public MustOverride Function Ddot ( _
	n As Integer, _
	x As Double(), _
	xOffset As Integer, _
	incx As Integer, _
	y As Double(), _
	yOffset As Integer, _
	incy As Integer _
) As Double
Visual C++ 
                      public:
virtual double Ddot(
	int n, 
	array<double>^ x, 
	int xOffset, 
	int incx, 
	array<double>^ y, 
	int yOffset, 
	int incy
) abstract
F# 
                      abstract Ddot : 
        n:int * 
        x:float[] * 
        xOffset:int * 
        incx:int * 
        y:float[] * 
        yOffset:int * 
        incy:int -> float

Parameters

n
Type: System..::..Int32
The number of elements in the vectors x and y.
x
Type: array<System..::..Double>[]()[][]
A reference to a one-dimensional array containing the elements of the vector x.
xOffset
Type: System..::..Int32
Offset into x.
incx
Type: System..::..Int32
The increment for the array x.
y
Type: array<System..::..Double>[]()[][]
A reference to a one-dimensional array containing the elements of the vector y. The elements of y are overwritten with the result.
yOffset
Type: System..::..Int32
Offset into y.
incy
Type: System..::..Int32
The increment for the array y.

Return Value

The dot product of the two vectors.
