If some matrix A has shape n-by-n, then its inverse matrix Ai is n-by-n and the matrix product of Ai * A is the n-by-n Identity matrix (1s on the upper-left to lower-right main diagonal, 0s off the ...

(2009) to target the diagonal elements of the sample covariance matrix. We derive the closed-form solution of the shrinkage parameter and show by simulation that, when the diagonal elements of the ...

Add a description, image, and links to the tri-diagonal-matrix-algorithm topic page so that developers can more easily learn about it.

Abstract: The singular value decomposition (SVD) factors a matrix into three separate matrices: two (semi-)unitary matrices whose columns are left/right singular vectors and one diagonal matrix whose ...

Abstract: This paper presents a kind of the inverse eigenvalue problem for the real five-diagonal matrix: Given three real numbers unequal, three nonzero real vectors, another n-2 real numbers as well ...

It has been shown that these so-called Mueller matrix images can help to distinguish geometrical features of nanostructures in the sub-wavelength regime due to visible differences in off-diagonal ...

In the case of quality, the upper-right quadrant of the 2 x 2 matrix is not just misleading; it does not exist. Quality exists on a diagonal. Here is a brand-business marketing tip: Get rid of the ...

The main diagonal starts at the left upper corner (index [0][0]). Every next cell of the diagonal is reached by going one step below and one step to the right (indices [x][x] - x being an integer ...
