JAVA 矩阵工具包 JAMA

JAMA is a basic linear algebra package for Java. It provides user-level classes for constructing and manipulating real, dense matrices. It is meant to provide sufficient functionality for routine problems, packaged in a way that is natural and understandable to non-experts.

package Jama;

   /** Cholesky Decomposition.
   

   For a symmetric positive definite matrix A the Cholesky decomposition
   is an lower triangular matrix L so that A = L*L‘.
   

   If the matrix is not symmetric or positive definite the constructor
   returns a partial decomposition and sets an internal flag that may
   be queried by the isSPD（） method.
