Im working with some roughly 100000x100000 hermitian complex sparse-matrices, with roughly 5% of entries populated, and want to calculate the eigenval ...
I'm trying to set up the Smile machine learning library in Java but I'm having some issues getting some dependencies to work. Currently I am on a Fedo ...
I have the same problem described here CVXPY Quadratic Programming; ArpackNoConvergence error. I would like to try the pertubation/trasformation solu ...
Given the following input numpy 2d-array A that may be retrieved with the following link through the file hill_mat.npy, it would be great if I can com ...
To find the 10 smallest eigenvalue of a sparse matrix 'A', the minimal code below works well: But when I change A to a complex sparse matrix, lik ...
I'm trying to use the Python package CVXPY to solve a convex quadratic programming problem of the first form here: https://www.cvxpy.org/examples/basi ...
For my problem I am only interested in few eigenstates (with smallest eigenvalues) of a sparse real symmetric matrix A. As far as I can see, arpack us ...
I am trying to install the 2.16 version of Calculix. When installing according to that described at (https://github.com/precice/calculix-adapter/wiki/ ...
I want to solve the following generalized EVP using the ArpackWrapper of the Eigen library: K_e is SPD. Normally K_g is indefinite and singular but ...
I'm trying to find the smallest (as in most negative, not lowest magnitude) several eigenvalues of a list of sparse Hermitian matrices in Python using ...
I have a 50,000 by 50,000 dense matrix or larger. If I use the numpy or scipy- packages the entries of all my eigenvectors are 0. If I use scipy.spars ...
I want to perform an SVD on a big array M[159459,159459]. Since SVD computation depends on the input matrix of shape (159459,159459), this here does ...
I was wondering if there is a way to calculate the first few eigenvectors of a very large sparse matrix in tensorflow, hoping that it might be faster ...
I am getting the following Warning when I run the PySpark job: 17/10/06 18:27:16 WARN ARPACK: Failed to load implementation from: com.github.fommi ...
I want to obtain numerically the energy of the ground state of some hermitian matrix (see the definition of this matrix in the following code) and plo ...
I tried to use ARPACK using some examples (here), but I could not even figure out how to input my matrix. From this question, It seems that the implem ...
I am applying spectral clustering to a dataset with 4200 rows and 2 columns. I have the below error. How do i increase the iterations of arpac ...
I am installing software on a server with no root privileges. I come across the following error during installation: Since library arpack could not ...
