Upper Triangular Matrix Vectorization Does PyTorch has the function that would return me the vectorized upper triangular matrix? For example, I have Tensors as [ [1, 2, 3], [4, 5, 6], [7, 8, 9]], and I want [1, 2, 3, 5, 6, 9]. 2, 3], [4, 5, 6], [7, 8, 9]...
(QR decomposition) If A is an m× n matrix, it can be expressed in the form A = QR, where Q is an m× m orthogonal matrix and R is an m× n upper triangular matrix. Now let us do Example 17.1 again, this time using the Givens QR decomposition. Compare the results to those of...
Upper triangular matrix groupWord mapsZariski topology2023 Elsevier Inc.Let p be a polynomial in non-commutative variables x1,x2,…,xn with constant term zero over an algebraically closed field K. The object of study in this paper is the image of this kind of polynomial over the algebra of...

triu(A) returns a triangular matrix that retains the upper part of the matrix A. The lower triangle of the resulting matrix is padded with zeros. triu(A,k) returns a matrix that retains the elements of A on and above the k-th diagonal. The elements below the k-th diagonal equal to ...
Denote by β = β(k) the measure of the noninvertible elements β(k) = η({a ∈ k | ∃ b, a b = 1}) For example, β(ކq ) = 1/q, and β(ޚp) = 1/p. Let G = U (n, k) be the group of upper triangular(n × n)-matrices over k with ones on diagonal. ...
I would like to have a square matrix (4x4) with this data where the upper triangular matrix is the percentage of similarity and the lower triangular matrix the times that were compared, like this: 0 50* 25 40 4* 0 25 40 4 4 0 40 ...

The sedimentary deposit of Cueva Millán consists of circa 1.1 m thick accumulation of sub-horizontally oriented, angular, limestone debris in a fine sand to silty matrix (Fig.4B; Supplementary Text3). The limestone debris has the same petrographic features as the cave wall and was much likely...
