Generate a matrix with given eigenvalues
WebWe start by finding the eigenvalue. We know this equation must be true: Av = λv. Next we put in an identity matrix so we are dealing with matrix-vs-matrix: Av = λIv. Bring all to left hand side: Av − λIv = 0. If v is non-zero … WebMar 4, 2024 · I am doing the following to generate random matrices with eigenvalues in a specific range: function mat = randEig (dim, rReal) D=diff (rReal).*rand (dim,1)+rReal (1); P=rand (dim); mat=P*diag (D)/P; end But I also want to be able to generate random real matrices with complex (conjugate) eigenvalues. How would one do that?

WebThis can be done by subtracting the sample mean of z ( z ∗ = z − z ¯) and calculating the Cholesky decomposition of z ∗. If L ∗ is the left Cholesky factor, then z ( 0) = ( L ∗) − 1 z ∗ should have sample mean 0 and identity sample covariance. You can then calculate y = L z ( 0) + μ and have a sample with the desired sample moments. WebThe eigenvalues of $\mathbf{B}$ should be less than one and I don't want to repeat random number generation process until this happens. I want to change some elements of a generated matrix (whose at least one of its eigenvalues is larger than one) so that all eigenvalues become less than one. Is there any way to do so?
WebAug 7, 2014 · As indicated in several of the comments, if v is an eigenvector of A, then so is α v for any α ≠ 0. Given an eigenvalue λ, there are thus infinitely many eigenvectors. Whatever solver you are using normalizes the eigenvectors, reducing this set to two possibilities; ± v where v = 1. The solver has no way of knowing which of these two … Web1st step. All steps. Final answer. Step 1/2. We know if matrix A has eigenvalue λ corresponding to eigenvector v then A v = λ v. Given Matrix has eigenvalues a and b correspondig to eigenvectors x and y respectively. ⇒ A x = a x and A y = b y. i) True.
