the reason being that symbol I is automatically translated by Mathematica to. Complex[0, 1] and rule above is interpreted by Mathematica as . Complex[0, 1] -> Complex[0, -1] However, when I apply it to a simple expression (say, 2 + 3 I), I am working with a different expression (in this case Complex[2, 3]), so the rule is not applicable. The conjugate transpose of an m×n matrix A is the n×m matrix defined by A^(H)=A^_^(T), (1) where A^(T) denotes the transpose of the matrix A and A^_ denotes the conjugate matrix. In all common spaces (i.e., separable Hilbert spaces), the conjugate and transpose operations commute, so A^(H)=A^_^(T)=A^(T)^_. (2) The symbol A^(H) (where the "H" stands for "Hermitian") gives official recognition Conjugate : Introduction to the complex components : Plotting : Evaluation: Complex Components: Conjugate[z] (90 formulas) Primary definition (1 formula) Specific values (31 formulas) General characteristics (5 formulas) Transformations (29 formulas) Complex characteristics (12 formulas) Differentiation (2 formulas) Representations through equivalent functions (9 formulas) Zeros (1 formula The conjugate can be very useful because.. when we multiply something by its conjugate we get squares like this: How does that help? It can help us move a square root from the bottom of a fraction (the denominator) to the top, or vice versa. Read Rationalizing the Denominator to find out more: Example: Move the square root of 2 to the top: 13−√2. We can multiply both top and bottom by Mathematica Stack Exchange is a question and answer site for users of Wolfram Mathematica. It only takes a minute to sign up. Sign up to join this community .

Ask Question Asked 4 years, 6 months ago. Active 4 years, 6 months The conjugate matrix of a matrix is the matrix obtained by replacing each element with its complex conjugate, (Arfken 1985, p. 210). The complex conjugate is implemented in the Wolfram Language as Conjugate [ z ]. Note that there are several notations in common use for the complex conjugate. Conjugate[z] or z\[Conjugate] gives the complex conjugate of the complex number z. ConjugateTranspose [m] is equivalent to Conjugate [Transpose [m]]. » can be entered as ct or \[ConjugateTranspose]. ConjugateTranspose [m] can also be given as , where can be entered as hc or \[HermitianConjugate]. ConjugateTranspose [m, spec] gives Conjugate [Transpose [m, spec]]. Mathematica is set up to deal with complex numbers, although there are some tricks one has to learn. The simplest way to enter i (square root of -1) is as I (upper case I). z = 2 + 3 I 2 + 3 Â Note that Mathematica writes I in lowercase in the output. Here's another example: Sqrt@-4D 2 Â Real & Imaginary parts, Magnitude (=absolute value) & Argument, and Complex Conjugate are obtained as
