Identity Matrix: In mathematics, a matrix is a rectangular array of numbers. The identity matrix is ann×nmatrix, most often denoted asI, such that for anyn×nmatrix,A,AI=IA=I. The identity matrix consists of ones along its diagonal and zeros everywhere else. ...
Positive definite matrix has a unique square root which is also positive definite. cube root n. pr. 立方根; take the cube root of x : 取 x 的(实)立方根 e.g. A cube root of x is a number y that when cubed equals x . nth root n. pr. n 次方根:take the nth root of x :取...
Let A be a square matrix satisfying A^2=A and let B be any matrix of the same size.Show that (AB-ABA)^2=0A是一个满足A^2=A的方矩阵,B是同样大小的任意矩阵.证明(AB-ABA)^2=0.应该是这个意思,请指点思路, 相关知识点: 试题来源: 解析 (AB-ABA)^2 =ABAB-AB*ABA-ABA*AB+ABA*ABA ...

To perform the reconstruction, A must be channelized into a Nch × Nch square matrix with a resolution grid of δλ = BW/(Nch − 1) and a scanning step of δP = Pmax/(Nch − 1). Here, Nch denotes the channel number, BW denotes the bandwidth, and Pmax...

To achieve a better trade-off between the element size and computation time, the area near the cutting zone (near the tool-tip) was modeled with a finer mesh of size 5 µm. In this approach, the initial geometry of the chip must be predefined with respect to the uncut chip thickness...
For a bounded domain with smooth boundary, we explicitly calculate the first two coefficients of the asymptotic expansion for the integral of the trace of the Stokes semigroup as . These coefficients (i.e., spectral invariants) provide precise information for the volume of the domain and the su...
