The WindowFunction type exposes the following members.

Constructors

  NameDescription
Public methodWindowFunction
Constructs a new window function.
Top
Properties

  NameDescription
Public propertyItem
Gets the component of the window function at the specified index.
Public propertyLength
Returns the length of the window.
Top
Methods

  NameDescription
Public methodEquals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodMultiply(VectorComplexDouble)
Applies the window to a complex vector.
Public methodMultiply(ComplexVector)
Applies the window to a complex vector.
Public methodMultiply(VectorDouble)
Applies the window to a vector.
Public methodMultiply(Vector)
Applies the window to a vector.
Public methodToArray
Returns the components of the window function as an array.
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodToVector
Returns the components of the window function as a vector.

Operators

  NameDescription
Public operatorStatic memberMultiply(WindowFunction, VectorComplexDouble)
Applies a window function to a complex vector.
Public operatorStatic memberMultiply(WindowFunction, VectorDouble)
Applies a window function to a vector.
Public operatorStatic memberMultiply(WindowFunction, ComplexVector)
Applies a window function to a complex vector.
Public operatorStatic memberMultiply(WindowFunction, Vector)
Applies a window function to a vector.

Remarks

Use the WindowFunction class to represent a function that can be applied to a signal to enhance certain characteristics of the signal. Window functions are also used in the design of finite impulse response filters.

Window functions have a lot in common with normal vectors. Vectors can be pre-multiplied by window functions. The length of the window function does not have to be the same as the length of the vector.

The WindowFunctions class contains methods that generate some of the more common window functions.
