conj
Complex conjugate
Syntax
Description
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
