根据对称矩阵的性质,存在可逆矩阵(非奇异,满秩)P,使得A = P B Pt,Pt是P的转置变换。在这种变化下,又称A 与 B 合同( congruence,相合)。关于矩阵合同有西尔维斯特惯性定理(Sylvester’s law of inertia): LetAbe a symmetric square matrix of ordernwith real entries. Any non-singular matrixSof the sam...
, where a a is a symmetric, positive definit matrix. let us denote the error by e 0 e 0 ; e 0 : = x − x 0 . e 0 := x − x 0 . furthermore, let the residual r 0 : = b − a x 0 . r 0 := b − a x 0 . we now want to make a correction step of ...

with multiple photons. the phase space representation of such a state would consist of four terms, two of which can be combine into a oscillatory term. ons can show this by computing the characteristic function as the trace of the density operator by an adjoint displacement...
the qubit, which is what you do when you want to get the effective density matrix of the system for all hermitian system-operators generating expectation values, and defining a = d t / 2 − − − − √ v ^ † a = d t / 2 v ^ † , this physical process corresponds to...

Every U238/U235 atom is assumed in QM to be in a superposition of the lighter and heavier isotope at least until it decays (and actually afterward as well since time is symmetric at the quantum level). That's the weirdness of QM. I've just been converted to the statistical (ensemble)...

You’re still there. The AES algorithm uses a pre-established matrix to mix the 4x4 columns of the data array. Another Round Key Addition The AES algorithm then repeats the second step, adding around key once again, then does this process all over again. ...
Correlation matrix is asquared(the number of rows equals the numbers of columns),symmetric(the matrix is equal to its transpose), with all the principal diagonal elements equal to 1 andsemidefinite positive(all its eigenvalues are non negative) matrix. While the first 3 properties are simple to...
