Complex.Conjugate Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Computes the conjugate of a complex number and returns the result.

Namespace:  System.Numerics
Assembly:  System.Numerics (in System.Numerics.dll)

Syntax

'Declaration
Public Shared Function Conjugate ( _
    value As Complex _
) As Complex

public static Complex Conjugate(
    Complex value
)

Parameters

Return Value

Type: System.Numerics.Complex
The conjugate of value.

Remarks

The conjugate of a complex number inverts the sign of the imaginary component; that is, it applies unary negation to the imaginary component. If a + bi is a complex number, its conjugate is a - bi.

Examples

The following example displays the conjugate of two complex numbers.

Imports System.Numerics

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim values() As Complex = { New Complex(12.4, 6.3), 
                                  New Complex(12.4, -6.3) }
      For Each value In values
         outputBlock.Text += String.Format("Original value: {0}", value) + vbCrLf
         outputBlock.Text += String.Format("Conjugate:      {0}",  
                           Complex.Conjugate(value).ToString()) + vbCrLf
         outputBlock.Text &= vbCrLf
      Next
   End Sub
End Module
' The example displays the following output:
'       Original value: (12.4, 6.3)
'       Conjugate:      (12.4, -6.3)
'       
'       Original value: (12.4, -6.3)
'       Conjugate:      (12.4, 6.3)

using System;
using System.Numerics;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      Complex[] values = { new Complex(12.4, 6.3), 
                           new Complex(12.4, -6.3) };
      foreach (Complex value in values)
      {
         outputBlock.Text += String.Format("Original value: {0}", value) + "\n";
         outputBlock.Text += String.Format("Conjugate:      {0}\n",
                           Complex.Conjugate(value).ToString()) + "\n";
      }
   }
}
// The example displays the following output:
//       Original value: (12.4, 6.3)
//       Conjugate:      (12.4, -6.3)
//       
//       Original value: (12.4, -6.3)
//       Conjugate:      (12.4, 6.3)
