Consider the following code, which calculates the roots of the polynomial `x^4` using the companion matrix eigenvalues:
```c#
var polynomial = new Polynomial(0, 0, 0, 0, 1);
var rootsReal = polynom…

Can you extend the code to solve Generalized eigenvalue problems
L\nu = \lambda W \nu
Currently, if I have to solve this, then, I would have to convert this to a standard eigenvalue problem, like,

While working on test data, I found that when `fcqs` is run on the real data from the Dropbox, it results in complex eigenvalues in `rigpower`, resulting in an error in `eval`.
This is the code I r…

I have a dataset with 5 samples and when I conduct pcangsd, I am unable to properly calculate the proportion of variation for each PC due to the presence of a negative eigenvalue.

I'm trying to play with some algorithms in the graph embedding literature (e.g. locality preserving projections) which need to solve the generalized eigenvalue. The Matlab 'eigs' function has this opt…

Introduction
In PR #13808, we use Principal Component Analysis (PCA) to calculate initial orientation of an oriented bounding box (OBB) of a point set. However, when the covariance matrix has repea…

I encounters infinite loop when i run a saga_gui.py
First, the torch version caused the following error in def pca.
TypeError: linalg_eig() got an unexpected keyword argument 'eigenvectors'
