How to tell if the matrix has eigenvalue 0? Let B=\begin{bmatrix} 1 & -2 & 0 & 4\\ 1 & 2 & 3 & -3\\ -1 & 1 & 4 & -1\\ 2 & 0 & 1 & 0 \end{bmatrix}, Determine whether each vector is an eigenvector of B: a) \begin{bmatrix} -1\\ 0\\ 0\\ 1 \e ...
Hello, I have a given eigenvalue (energy) of my matrix (Hamiltonian), which is known. Now I want to obtain the eigenvector associated with it? Is there any function similar to eig to do so? Thanks in advance. 댓글 수: 0 ...
Hello, I am trying to code a principal component analysis (PCA) on a dataset (8 samples , 2 features) and I can not plot the datapoints' projections on the eigenvector which provide the largest variace (eigenvector of the 1st principal component). The code is as following: ...
Update: I have resorted to using a Jacobi method for matrices for the eigen-decomposition ot the matrix. This seems to be a solid parallel algorithm at the very least. When I finish I will have to test it against matlabs implementation of eigen-decomposition and against a cpu based Jacobi...

The eigenvalues of a square matrix A are the valuesλsuch that Av→=λv→, wherev→are the eigenvector corresponding to the eigenvalueλ. To find the eigenvalues, we will solve the algebraic equationdet(A−λI)=0. Knowing the eigenvalues and eigenvectors of a matrix, is needed in w...
