We discuss stability of square root domains for uniformly elliptic partial differential operators La,Ω,Γ=−∇⋅a∇ in L2(Ω), with mixed boundary conditions on ∂Ω, with respect to additive perturbations. We consider open, bounded, and connected sets Ω∈Rn, n∈N\{1}, that satis...
我正在寻找最快的方法来确定一个 long 值是否是一个完全平方数(即其平方根是另一个整数):我已经用内置的Math.sqrt()函数轻松完成了它,但我想知道是否有一种方法可以通过限制自己到整数域...Fastest way to determine if an integer's square root is an integer
Different from the traditional UKF, the square-root of the state covariance matrix is directly propagated in the SRUKF method, avoiding the need to calculate the square-root of the state covariance at each iteration step. The SRUKF is more advantageous with better numerical properties and guaranteed...
