Complex-Valued Matrix Differentiation: Techniques and Key Results A systematic theory is introduced for finding the derivatives of complex-valued matrix functions with respect to a complex-valued matrix variable and the c... A Hjorungnes,D Gesbert - 《IEEE Transactions on Signal Processing》 被引量...
In this paper, the use of complex differentiation is presented as a robust and concise tool for modeling and sensitivity analysis of large-scale electrical networks. A complex power flow model was employed to determine the network’s operating point, from which the sensitivity analysis of the elec...
The density matrix is a fundamental concept in quantum statistical physics. In quantum mechanics, when a system is in its initial state, its description relies on a wave function or a state vector. However, when the system is in a mixed state, its representation shifts to a density matrix....
