java.lang.ObjectJampack.Zchol
public class Zchol
Zchol implements the Cholesky decomposition of a positive definite matrix. Specifically if A is (Hermitian) positive definite then there is an upper triangular matrix R with positive diagonal elements such that
A = R^H RThe matrix R is implemented as a Zutmat.
