For a given matrix subspace, how can we find a basis that consists of low-rank matrices? This is a generalization of the sparse vector problem. It turns out that when the subspace is spanned by rank-1 matrices, the matrices can be obtained by the tensor CP decomposition. For the higher...

In summary, the conversation discusses finding the matrix representation of a linear transformation and using it to find the eigenvalues and formula for a given polynomial. The process involves applying the transformation to basis vectors and converting it into B-coordinates. The resulting matrix is ...

Pivoting matrix: if a multiple of equation i is added to equation j, put the number k at the position (row=j, col=i) of an identity matrix. 5 multiply row 2 added to row 1. (Image by Author) We now can use the elementary matrices to find an inverse matrix. ...
I have a 3x3 Matrix A.I was asked to find A^n.I found it using eigenvalues/Eigenvectors and the fact thatA^n=P.B^n.(P^-1) with B the diagonal matrix and P the basis of the eigenvectors.Then The question isFind the Limit of ...
This paper presents a hybrid variational quantum algorithm that finds a random eigenvector of a unitary matrix with a known quantum circuit. The algorithm
M Pagitz,JMM Tur - 《International Journal of Solids & Structures》 被引量: 86发表: 2009年 Stiffness matrix based form-finding method of tensegrity structures A highly efficient form-finding method of tensegrity is presented on the basis of the structural stiffness matrix, which is defined as ...
In summary, the solution to finding all matrices X such that A\cdot X = A' with the 2nd and 4th column swapped is to use matrix column operations. This method allows you to solve for X in a systematic way and does not depend on any assumptions about the values of the elements in X...
The ROM matrix is in general full, and not good for extracting the potential. However, using an orthogonal change of basis via Lanczos iteration, we can transform the ROM to a block triadiagonal form from which it is easier to ... L Borcea,V Druskin,AV Mamonov,... 被引量: 0发表:...
