conj

Complex conjugate

Syntax

Zc = conj(Z)

Description

Zc = conj(Z) returns the complex conjugate of each element in Z.

Examples

Find Complex Conjugate of Complex Number

Find the complex conjugate of the complex number Z.

Z = 2+3i

Z = 2.0000 + 3.0000i

Zc = conj(Z)

Zc = 2.0000 - 3.0000i

Find Complex Conjugate of Complex Values in Matrix

Create a 2-by-2 matrix with complex elements.

Z = [0-1i 2+1i; 4+2i 0-2i]

Z = 2×2 complex

   0.0000 - 1.0000i   2.0000 + 1.0000i
   4.0000 + 2.0000i   0.0000 - 2.0000i

Find the complex conjugate of each complex number in matrix Z.

Zc = conj(Z)

Zc = 2×2 complex

   0.0000 + 1.0000i   2.0000 - 1.0000i
   4.0000 - 2.0000i   0.0000 + 2.0000i

Input Arguments

Z — Input array

scalar | vector | matrix | multidimensional array

Input array, specified as a scalar, vector, matrix, or multidimensional array. conj operates element-wise when Z is nonscalar.
