实对称矩阵特征值与特征向量的雅克比法，ap为是对称矩阵，vp返回特征向量(Real Symmetric Matrix Eigenvalues and Eigenvectors of the Jacobian method, ap is a symmetric matrix, vp return eigenvector)

The solver was mdae to solve the teat tansfrer fields with cooling and hot zone. The Gauss-seidial, ADI, Laasonnen, and Crank-Nicolson schemes are present in the code. You can handle the method you want, iteration and the level of tolerance. The code was made at the LINUX platform. Let me know if you need assistance.

可以实现十几位整数的四则运算，效率也较好(Four operations can be more than a dozen integer,and the efficiency is better)

最小二乘曲面拟合程序（m文件），对一组三维数据z=f(x,y)拟合，成为关于x和y的多项式(least squares fitting procedure Surface (m), a group of three-dimensional data z = f (x, y) fitting, be on the x and y polynomial)

说明：  常见的空间转化代码，将彩色空间从BGR 转换到HSV，LAB等(Common space conversion codes, converting color space from BGR to HSV, lab, etc)

ICP迭代最近点算法的各种实现方法，包括四元函数法，最小迭代，等算法，以及ICP迭代最近点算法的实现。(ICP iterative closest point algorithm implementation, including the four-function method, the minimum iteration algorithm, and ICP iterative closest point algorithm.)

说明：  用于在数值分析中，对于离散点进行拉格朗日差值拟合(Lagrangian difference fitting)

采用数值分析课程中的插值逼近以及曲面拟合方法来估算复杂的函数表达式。(Interpolation approximations and surface fitting methods are used in the numerical analysis course to estimate complex function expressions.)

用C++编写的大整数计算的模板，可实现加、减、乘、除、取模等运算，可以通过此源码学习高精度的实现。(Written with C++ template large integer can be realized addition, subtraction, multiplication, division, modulus and other operations, you can achieve high-precision study of this source.)

多物理场耦合软件采用有限元方法模拟表面等离子体激元，适合入门学习者(Multi-physics coupling software using the finite element method to simulate the surface plasmon, suitable for entry-learners)
