VectorExtensionsPercentChange Method

Extreme Optimization Numerical Libraries for .NET Professional
Returns a vector whose observations are the percent change of the observations over the specified lag.

Namespace:  Extreme.DataAnalysis
Assembly:  Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.1
Syntax

C#
VB
C++
F#
Copy
public static Vector<double> PercentChange(
	this Vector<double> vector,
	int lag
)
<ExtensionAttribute>
Public Shared Function PercentChange ( 
	vector As Vector(Of Double),
	lag As Integer
) As Vector(Of Double)
public:
[ExtensionAttribute]
static Vector<double>^ PercentChange(
	Vector<double>^ vector, 
	int lag
)
[<ExtensionAttribute>]
static member PercentChange : 
        vector : Vector<float> * 
        lag : int -> Vector<float> 

Parameters

vector
Type: Extreme.MathematicsVectorDouble
The vector to transform.
lag
Type: SystemInt32
An integer larger than zero that specifies the distance between the current observation and the reference observation.

Return Value

Type: VectorDouble
A vector.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type VectorDouble. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Exceptions

ExceptionCondition
ArgumentOutOfRangeExceptionlag is less than or equal to zero.
Remarks

The new vector gets the name changePct<n>(<name>), where <name> is the name of the original vector and <n> . is the length.
