When a scalar real-valued function depends on a complex-valued matrix parameter, the necessary conditions for optimality can be found by either setting the derivative of the function with respect to the complex-valued matrix parameter or its complex conjugate to zero. Using a matrix X in a similarity transformation X^(-1)AX of a given matrix A is also known as … For example, if we have ‘a + ib’ as a complex number, then the conjugate of this will be ‘a – ib’. Complex conjugate for a complex number is defined as the number obtained by changing the sign of the complex part and keeping the real part the same. }}}$$ means $${\displaystyle e^{i\varphi }+e^{-i\varphi }}$$. For example, the solvability of a real Sylvester matrix equation can be characterized by matrix similarity; however, the solvability of the con-Sylvester matrix equation in complex conjugate form is related to the concept of con-similarity.

The second is preferred in physics, where dagger (†) is used for the conjugate transpose, while the bar-notation is more common in pure mathematics. We need to consider what the cofactor matrix corresponds to. Communications and Control Engineering It proposes useful approaches to obtain iterative solutions or explicit solutions for several types of complex conjugate matrix equation. A conjugate matrix is a matrix A^_ obtained from a given matrix A by taking the complex conjugate of each element of A (Courant and Hilbert 1989, p. 9), i.e., (a_(ij))^_=(a^__(ij)). Wu, Ai-Guo, Zhang, Ying. numpy.matrix.conjugate¶ matrix.conjugate ¶ Return the complex conjugate, element-wise. It observes that there are some significant differences between the real/complex matrix equations and the complex conjugate matrix equations. In addition, the new concept of conjugate product for complex polynomial matrices is also proposed in order to establish a unified approach for solving a type of complex matrix equation. The operation also negates the imaginary part of any complex numbers. The complex conjugate of a complex number $${\displaystyle z}$$ is written as $${\displaystyle {\overline {z}}}$$ or $${\displaystyle z^{*}\!}$$. A conjugate matrix "A" is the matrix taking the complex conjugate of each element of "A". (array), is that complex conjugation is a standard, well-defined mathematical operation on any complex vector space, as opposed to a function like sin. / Matrix Transform. For example, the solvability of a real Sylvester matrix equation can be characterized by matrix similarity; however, the solvability of the con-Sylvester matrix equation in complex conjugate form is related to the concept of con-similarity. When b=0, z is real, when a=0, we say that z is pure imaginary. 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.
