This collection of C++ templates wraps the FORTRAN or C interfaces for LAPACK so that they integrate with the Boost uBLAS library. Currently implements Cholesky decomposition, LU decomposition, inversion and determinant for general and positive-defin

此方法为求解线性方程组的方法，LU分解法也称Doolittle分解法方便，是数值计算中经常运用的一种方法-This method is the method for solving linear equations, LU decomposition, also known as Doolittle decomposition method is convenient, is often used in numerical calculation method

In linear algebra, the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, useful for efficient numerical solutions an

In the mathematical discipline of linear algebra, a triangular matrix is a special kind of square matrix. A square matrix is called lower triangular if all the entries above the main diagonal are zero. Similarly, a square matrix is called upper trian
