tail conditional expectationcapital allocationCorrelation functions $C(t) \\sim $ in ohmically damped systems such as coupled harmonic oscillators or optical resonators can be expressed as a single sum over modes $j$ (which are not power-orthogonal), with each term multiplied by the Petermann ...
std::cout << "The number of elements in the vector greater than " << threshold << " is: " << count << std::endl; return 0; } ``` 在上面的示例代码中,我们首先创建了一个大小为 5 的向量 `vec`,并初始化其元素为 1 到 5。然后我们选择了一个阈值 `threshold`,并使用 Eigen 库提供的...

Principal eigenvector components in the star k1,k. The ratio c=∑u∈NK1,k(w)xu/xw is then equal to k/λ1, so that λ1 and the spectral radius μ1 of H are related by the equation λ1−kλ1=μ1, which implies that λ1=μ1+μ12+4k2. Example 2.2 Now, let λ1 and ...

(Interestingly, the lobpcg version of Scipy works for that same initial vector X) @pearu@nikitaveddo you know what could be going on here? Perhaps there's a bug in the way we useX? I have two notes: torch.lobpcgexpectsXto be a random tensor with random numbers from a normal distribut...

Given a real vector x=(x1,x2,…,xn)∈Rn, we rearrange its components as x[1]⩾x[2]⩾⋯⩾x[n]. For x=(x1,x2,…,xn), y=(y1,y2,…,yn)∈Rn, if∑i=1kx[i]⩽∑i=1ky[i],k=1,2,…,n, then we say that x is weakly majorized by y and denote x≺wy. If ...
