Web1 de nov. de 2024 · The phases of A, denoted by ϕ ( A), are defined as the phases of the eigenvalues of D, and the latter are defined to belong to an interval of length less than π. Without loss of generality we will always order the phases nonincreasingly, i.e., ϕ 1 ( A) ≥ ϕ 2 ( A) ≥ ⋯ ≥ ϕ n ( A), where 0 ≤ ϕ 1 ( A) − ϕ n ( A) < π. WebHá 1 dia · cmath. phase (x) ¶ Return the phase of x (also known as the argument of x), as a float. phase(x) is equivalent to math.atan2(x.imag, x.real). The result lies in the range [-π, π], and the branch cut for this operation lies along the negative real axis. The sign of the result is the same as the sign of x.imag, even when x.imag is zero:
