1. 无实根 2. “共轭复数根”是对的，但不一定是“.二共轭复数根”，因为不一定是二次函数。当然讲“共轭”太深奥了，其实complex conjugate roots 就是指一个函数有多个根
and they are called the complexnth roots of unity. If a regular polygon ofnsides is inscribed in a unit circle centred at the origin so that one vertex lies on the positive half of thex-axis, the radii to the vertices are the vectors representing thencomplexnth roots of unity. If the ...

Computation of roots of real and complex matricesAn algorithm is presented in this paper by which the rth root of real or complex matrices can be found without the computation of the eigenvalues and eigenvectors of the matrix. All required computations are in the real domain. The method is ...
Furthermore even on serial computers the acceleration is dramatic for numerical approximation of the real roots in the typical case where they are much less numerous than all complex roots.Pan, Victor YZheng, AiLongPan, V.Y., Zheng, A.: New progress in real and complex polynomial root-...

Modern Fortran library for finding the roots of real and complex polynomial equations - jacobwilliams/polyroots-fortran
We combine the known methods for univariate polynomial root-finding and for computations in the Frobenius matrix algebra with our novel techniques to advance numerical solution of a univariate polynomial equation, and in particular numerical approximation of the real roots of a polynomial. Our analysis...
The Use of a Repetitive Differential Analyzer for Finding Roots of Polynomial Equations The paper describes a procedure for obtaining real and complex roots of algebraic equations with real or complex coefficients by the use of a repetitive di... P Madich,J Petrich,N Parezanovich - 《Electronic...
1) Real & conjugated roots 实根和共轭根2) conjugate complex roots 共轭复根 1. According to the conditions of orthogonal wavelet construction, the complex wavelets are constructed by replacing the conjugate complex roots,which,compared with dbN real orthogonal wavelets,have the same amplitude ...
