Definition
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
Overload List
Combine | Constructs a delegate that represents a multivariate function returning a matrix in its second argument from an array of multivariate functions returning a vector. |
Combine | Constructs a multivariate function returning a vector in its second argument from an array of multivariate function delegates. |
Combine | Constructs a delegate that represents a multivariate function returning a matrix in its second argument from an array of multivariate functions returning a vector. |
CombineFast(Func<Vector<Double>, Vector<Double>>[])
public static Func<Vector<double>, Matrix<double>, Matrix<double>> CombineFast(
this Func<Vector<double>, Vector<double>>[] functions
)
Parameters
- functions Func<Vector<Double>, Vector<Double>>[]
- An array of multivariate functions returning a vector.
Return Value
Func<Vector<Double>, Matrix<Double>, Matrix<Double>>A delegate that returns a matrix whose rows correspond to the return values of the elements of functions
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type Func<Vector<Double>, Vector<Double>>[]. 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).Remarks
Use this method to combine several multivariate vector functions into one Func<T1, T2, TResult> that returns a matrix whose rows contain each of the function values.
Note that there is a slight performance loss over defining the Func<T1, T2, TResult> directly because of the overhead of invoking multiple delegates instead of one.
CombineFast(Func<Vector<Double>, Double>[])
public static Func<Vector<double>, Vector<double>, Vector<double>> CombineFast(
this Func<Vector<double>, double>[] functions
)
Parameters
Return Value
Func<Vector<Double>, Vector<Double>, Vector<Double>>A multivariate function returning a vector whose return values correspond to the return values of the elements of functions
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type Func<Vector<Double>, Double>[]. 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).Remarks
Use this method to combine several multivariate functions that return a real number into one multivariate function returning a vector in its second argument that returns a vector containing each of the function values.
Note that there is a slight performance loss over defining the multivariate function returning a vector directly because of the overhead of invoking multiple delegates instead of one.
