SignalProcessingExtensions.InverseDiscreteCosineTransform Method

Computes the inverse discrete cosine transform (iDCT) of a vector.

Definition

Namespace: Numerics.NET.SignalProcessing
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.6
C# 
public static Vector<double> InverseDiscreteCosineTransform(
	this Vector<double> x,
	bool orthonormal = true
)

Parameters

x  Vector<Double>
The vector to transform.
orthonormal  Boolean  (Optional)
Optional. Specifies whether the transform should be orthogonal/unitary. The default is true.

Return Value

Vector<Double>
The inverse discrete cosine transform (iDCT) of x.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type 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).
