1.通过这次实验，我掌握了使用Gauss消去法解线性方程组的方法，加深了我对Gauss消元法的理解。2.Gauss消元法还可以改进，可衍生出列主元消去法和平方根法等，达到减少计算量和减小误差的作用使结果更加准确。3.迭代过程中要求主对角线元素不为零，这在一定程度上限制了可解的线性方程组。

粒子群优化算法（PSO,particle swarm optimization）是计算智能领域，除了蚁群算法，鱼群算法之外的一种群体智能的优化算法。函数寻优是工程中经常遇到的问题，有些函数因为局部极小值点的存在，算法难以寻找到局部最优值。粒子群算法具有群体智能，全局寻优等优势，比较适合于函数寻优问题，本案例研究了基于粒子群算法的函数寻优算法。

利用Gauss积分公式进行数值积分，将区间 细分成n个相等的子区间，然后在每个上使用经过修改适用于不同子区间的三点Gauss公式计算积分的值，然后求和。-Using Gauss integral formula for numerical integration, will be subdivided into n-equal interval sub-intervals, and then apply to each use of a modified three-point range in different sub-Gauss formula to calculate the value of points, and then summed.

! 2 ! HOMPACK90 is a suite of FORTRAN 90 subroutines for solving nonlinear 3 ! systems of equations by homotopy methods. There are subroutines for 4 ! fixed point, zero finding, and general homotopy curve tracking problems, 5 ! utilizing both dense and sparse Jacobian matrices, and implementing 6 ! three different algorithms: ODE-based, normal flow, and augmented 7 !

用希尔算法实现的排序-Hill with the ranking algorithm

自己编写的基于morlet小波的连续小波变换，可以修改其中参数.几个变量为输入变量，分别指信号，信号的长度以及分解的层数。输出变量，分别指小波变换的系数，频率以及尺度。就是对信号nLevel层小波变换。在实际使用的时候，只要把输入量给定，然后直接调用这个函数.但是输出与matlab自带的函数有出入，在修正中,使用的时候自己琢磨符不符合你的输入输出要求，进行算法的验证在我的程序里头是可以使用的。
