java.lang.Objectnet.talvi.puffinplot.data.Eigens
public class Eigens
A class to calculate and store the eigenvalues and eigenvectors of a matrix. It can also construct an orientation matrix from a supplied collection of vectors and perform eigen analysis on that matrix.
| Constructor Summary | |
|---|---|
Eigens(Matrix matrix)
Create an object holding the eigenvectors and eigenvalues of the supplied matrix. |
