Parameters

- Type: SystemFuncVectorDouble, Double
An array of
multivariate function delegates.
Return Value
Type:
FuncVectorDouble,
VectorDouble,
VectorDoubleA multivariate function returning a vector whose return values correspond to the
return values of the elements of
functionsUsage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type . 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).
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.
