All Implemented Interfaces:

ISparseEquation, ISparseEqnDouble

public class CSJSparseEqnDoubleImpl
extends AbstractSparseEqnDoubleImpl

CSJ Sparse Equation of data type double for solving the [A]X=B problem. To outside, the index number is from 0 to n-1. When [A] is a square matrix, LU decomposition method is used to solve the eqn When [A] is a non-square matrix, QR decomposition method is used to provide a Least Square or Weighted Least Square solution
