Discover how this award-winning travel photographer used light, timing, and Nikon gear to craft a quietly powerful image ...

We propose a stable and efficient divide-and-conquer algorithm for computing the eigendecomposition of a symmetric tri-block-diagonal matrix. The matrix can be derived from discretizing Laplace ...

.cofactor() Returns the cofactor of the matrix. .copy() Returns a copy of the matrix. .cut() Returns a smaller matrix by removing the required row and column. The default of row and column is None.

Reconfigurable intelligent surface (RIS) architectures not limited to diagonal phase shift matrices have recently been considered to increase their flexibility in shaping the wireless channel. One of ...

where S denotes a symmetric and positive definite matrix, D denotes a diagonal matrix and U an unitary upper triangular one. Assumption 4 The sign of the leading principal minors of KT are known. Then ...

In honor of the exhibition, the facade of the 57th Street boutique will feature Lagerfeld’s Fendi archive sketches, emblazoned across three floors of windows on digital screens. In addition, 15 ...

We study several variants of decomposing a symmetric matrix into a sum of a low-rank positive semidefinite matrix and a diagonal matrix. Such decompositions have applications in factor analysis and ...

Hi, I'm working on a MCMC estimation algorithm by using "RcppArmadillo", but got the error message "warning: chol (): given matrix is not symmetric" and the algorithm stops due to this issue.

2 A SINGLE MATRIX OF ORDER N: EIGENVECTORS AND OFF-DIAGONALIZING VECTORS The diagonalization of a real symmetric square matrix 𝕄 can be viewed as an optimization problem. One should find a ...
